Season 3: Dinosaur Origin — Last Z: Survival Shooter Guide

Here is the thing most players get wrong, and it is the same mistake that cost people the whole of Season 2: your first week determines your last week. Season 3 is built on compounding loops. Every day your Biotech Lab is behind is a day you are farming lower-tier dinosaurs, which means fewer Cretaceous Scales, which means an even slower Biotech Lab. That gap does not close on its own.

This guide is organised so you can read the first three sections before the season starts, then come back to the rest as each system unlocks. Use the feature list on the left to jump between topics — each panel is self-contained so nothing else on the page distracts you while you read.

Meet the three new S3 heroes

Three S-rarity seasonal heroes release across the first six weeks, each with their own battle pass and an exclusive signature weapon. At Lv.175 they are near-identical on raw stats — pick by role, not by numbers.

Blood Rose

Licia

Wyrm Wrath

All-rounder

Wings of Dawn

Liliana

Firefall

Burst DPS

Guard of Order

Dodomeki

One-Hit Kill

Sustained DPS

Release order: Licia first, then Liliana, then Dodomeki. Full stat comparison, signature skills and localisation notes are in GUIDE-03 · Season Heroes.

Season 3 is not a replacement for the Everfrost systems. It is a reskin plus expansion. The core loop is identical: kill map creatures, bank a seasonal resource, feed it into a resistance building, unlock higher-tier creatures, repeat.

If you ran Everfrost properly, this table is the fastest way to get oriented. Everything on the left behaves the way its Season 2 counterpart did.

What is genuinely new

• Hatch of Legends — a dinosaur companion you raise across the whole season for a permanent-until-season-end troop attack bonus
• Trade Hubs — capturable alliance structures that print diamonds, contested three times a week
• Fossil Album — a 20-slot collection track fed by the Sunday world boss
• Hero Level Swap — permanently move levels and skill investment from an old hero onto a new one
• Specialization to level 70 — an entire second tier of talents above the old level 50 cap

The mistake almost everyone makes: rushing troop-stat buildings in the opening 48 hours because the numbers look good. Low virus resistance locks you out of high-level dinosaurs, and high-level dinosaurs are where the glory points, badges and scales actually come from. Attack stats on a small income is a worse account than modest stats on a large one.

If you are only buying one thing: Wartime Investment ×4. The fifth Greenhouse compounds for thirteen weeks and the virus resistance is meaningful on day one.

If you are buying two: add Season Journey. The Glory Chest doubling is the largest single reward multiplier in the season.

Missing a hero pass is not fatal. After the initial six-week release window, the hero passes rotate into hero and exclusive weapon fragments. You can still assemble them later. Do not panic-buy a hero on their release week purely out of fear of missing out.

Planning HQ levels alongside your seasonal buildings? Our HQ upgrade calculator will tell you what each level actually costs before you commit.

Fern Leaves are passive and predictable. Cretaceous Scales are the bottleneck, because they come from active farming and the Biotech Lab consumes them in bulk. If your Lab is stalled, it is almost always Scales you are short of — which means your daily farming routine is the thing to fix, not your spending.

Release order & role

Stat comparison at Lv.175

Figures below are taken directly from our own account in-game, all three heroes at identical level and comparable gear, so the numbers are directly comparable to each other.

What this actually tells you: the three are near-identical on raw stats. Licia carries a marginal edge — about 2,250 power, 20 attack, 20 defense and 10 lethality over the other two — which at this scale is a rounding error, not a tier difference. Liliana and Dodomeki are statistically identical.

So do not pick your seasonal hero on the stat sheet. The meaningful differences are in skills and role, not base numbers:

• Liliana for the Sunday Ancient Dino window and any short burst-damage race — her high damage factor is where her value sits, and it does not show up in a base stat line.
• Dodomeki for sustained engagements, where normal attack boosts and per-hit scaling compound over a longer fight.
• Licia as the reliable all-rounder and the one most players will have deepest investment in, since she released first.

If you are only going to fully invest in one, invest in the one you actually have the most fragments for. A 20-point attack gap is worth far less than one extra star level.

A note on names: hero naming differs between regional versions of the game. Our state runs Licia / Liliana / Dodomeki; other regions show the same three heroes as Yu Chan / Queenie / Amber. The factions, release order, weapons and roles are identical — match by faction icon rather than by name if a guide you are reading does not line up with your client. For deeper per-hero breakdowns, see our heroes reference.

Signature skills (community-verified)

Skill data below is cross-checked against community wikis. Liliana's numbers match on two independent sources (mmediamreza and last-z.wiki) so treat them as reliable. Licia's kit is confirmed on structure and Bella synergy across three sources; the exact damage-factor progression is community-reported. Dodomeki is currently single-sourced — treat as provisional until a second data set appears.

Hero Level Swap

Available all season, and one of the most powerful systems in the game when used deliberately. Using a Level Swapper, you exchange progress between two heroes — the visual below shows the shape of a typical swap, and the rule cards cover every edge case in one glance.

Practical use: a level 150 legacy hero with maxed skills and a level 1 new meta hero become a level 1 legacy hero and a level 150 meta hero, with skills carried across if rarities match. Check rarity, star level and skill unlock requirements before swapping, and time swaps around events and PvP windows rather than mid-war.

Below level 30: you are Support by default.
Level 30 and above: you choose between Support and Combat.

When to switch: once your Biotech Lab clears level 60 dinosaurs comfortably and your Greenhouses are stable — typically somewhere in the middle third of the season. If you are primarily a war player, that is your moment. If you are primarily an economy player, staying Support the whole way is defensible.

Season tasks start by teaching the core loop: kill the first low-level dinosaurs, place both Bio Greenhouses, then build and level the Biotech Lab. Each visible starter objective pays 1,000 Fern Leaves and 1,000 Cretaceous Scales, so claiming as you go helps fund the next step.

Your alliance score is the sum of every member's Personal Glory plus the season points earned from captured cities. First kills of Velociraptors and Stegosauruses add Personal Glory. Cities add points over time, and the points already banked remain even if the alliance later abandons a city.

Do not mix up the reward pools: event and personal ranking rewards are mailed to the qualifying player. Alliance season-ranking chests are a separate pool handled through the alliance reward screen and distributed by alliance leadership.

State Ruler lasts seven days. Your rank is locked from your first Velociraptor kill: higher-level kills rank above lower-level kills, and an earlier kill wins only when players are tied on level.

Weekly tasks and season challenges award Journey EXP. That EXP raises the track level and unlocks the free reward lane. The optional General Certificate opens Prime Rewards and adds a 50% task EXP bonus, making it a speed-up rather than a requirement to claim the free path.

The early track shows useful season resources, diamonds, blueprints, building speedups and other progression materials. Check the task and target tabs before spending: normal play may already cover the next milestone.

A massive dinosaur spawns and the entire state attacks it with no attack limit. On an active server the boss dies in roughly 5 to 15 minutes. Logging in at 12:05 is a genuine risk of missing it entirely.

The five bosses

The boss rotates weekly across five species: T-Rex, Triceratops, Pterosaur, Ankylosaurus and Dimetrodon. (Some regional versions render the last two as Ankylosaurs and Demitradon.)

Titles — read this carefully

Each species carries a unique profile title. The top 3 damage dealers on the first-ever kill of that species on your server receive it permanently. Once a species has been killed for the first time on your server, no title is issued when it comes around again.

So if you are chasing a title, the play is to find out which species your server has not yet defeated and save your buffs, best hero and strongest march for that week specifically. Every other week is a farming week.

Getting the most damage out of the window

• Park your strongest march near the spawn before the timer hits zero. You want to be swinging in the first seconds, not marching.
• Hold your buffs until the last moments before spawn. Attack buffs fired five minutes early are wasted — there is no "later" in a fifteen-minute event.
• Virus resistance caps your contribution. A neglected Biotech Lab plateaus your damage regardless of troop power.
• Bring the burst hero. Of the three seasonal heroes, Liliana (Wings of Dawn) is built for high single-target burst and is the strongest pick for a short damage window.
• Cannot solo? Join a rally. Rally participation still counts toward your personal fossil drops and rewards.

Rewards

Rewards arrive in your in-game mail. Even a mediocre damage run is worth logging in for — the fossils are the point, and missing weeks back to back is what actually stalls your album.

Instead of hunting wild creatures, you intercept armed Predator Squads transporting dinosaurs and take the cargo.

• Targets: Predator Squads, levels 1–200
• Limits: 2 kills per day Monday–Saturday, 5 kills on Sunday
• Drops: seasonal resources, Ancient Dino Eggs, blueprints, Hero EXP, Pine Cones

Sunday: Black Market Guardian

Up to level 350. This is a rally target — it is not soloable by anyone, and it is not meant to be.

Ranking is by damage dealt, but the important mechanic is statewide achievement rewards: as the state collectively pushes the boss further, rewards unlock for everyone, not just top damage. Exclusive equipment fragments, orange hero fragments, recruitment tickets, fuel and Dino Feed.

This changes the incentive completely. Holding back your hits to protect a placement actively costs you, because the statewide thresholds pay more than the ranking spread does. Push participation in state chat, help fill rallies, and treat it as a cooperative event rather than a competitive one.

Waves of dinosaurs assault your headquarters and you defend. Compared to Zombie Siege it is tuned harder: more burst-damage enemies, stronger elite units, and much less forgiveness for a poorly built troop composition.

Prioritise completion over ranking. Completion rewards substantially outweigh placement rewards, and maximum clear pays out 14 Golden Wrenches — the highest-value single payout available from a repeatable event this season. (Some community sources translate this reward as "Golden Keys"; it is the same item under a different localisation.)

What the Boom changes

Once live, killing Velociraptors and Stegosaurus produces 2× Cretaceous Scales.That is a direct boost to your Biotech Lab progression and building upgrades.

The egg side is less certain. Some sources report doubled Ancient Dino Eggs alongside the scale boost; others report a 50% reduction in daily egg drops. Treat it as a trade window, not a free bonus.

How to play it

• Verify your own drop rates in the first 24 hours after the Boom activates. Server patches and regional builds have changed this modifier before.
• Pre-stockpile eggs before the midpoint if you are saving for a big Bio Institute Shop weekend.
• Burn stamina items through the Boom window — the scale gain is guaranteed and Biotech Lab levels compound for the rest of the season.
• Do not skip Predator Squad kills just because the modifier is up; capped income stays capped.

Spend Pet Feed to choose a T-Rex, Triceratops or Ankylosaurus egg. Feed then accelerates growth, while five time-limited tasks refresh daily and supply more feed.

All three choices follow the same rule set: growth grants attribute bonuses and adulthood unlocks that species' special vehicle skin. Both the bonuses and skin are removed when Season 3 ends. The live progression screens place the skin unlock at Dino Egg level 16.

Completing the full album pays out orange hero fragments, exclusive equipment fragments and a large stack of Ancient Dino Eggs.

The part most players miss: there is a second progress bar running alongside the 20 slots. Every fossil piece you collect — including duplicates — adds points to a milestone track that unlocks reward tiers at set thresholds, paying out resource bundles, blueprint chests and speedup packs long before the album is full. You are being paid the entire way, not only at the finish line.

Duplicates are never wasted. Any fossil you already own converts directly into Ancient Dino Eggs, which feed the Bio Institute Shop. This is why every Sunday run is productive regardless of outcome: you are either filling a slot or banking shop currency.

This is the highest-value place in the season to convert eggs into power, and the failure mode is spending badly rather than spending too little.

Buy priority

1. Exclusive equipment fragments — hardest to obtain anywhere else, so they carry the most marginal value
2. Orange hero fragments — core long-term progression
3. Badges — useful, but obtainable from Glory Chests and Trade Hubs, so lowest priority here

Refresh discipline

The stock is randomised. Fourteen refreshes sounds generous and disappears quickly.

• Scan the initial inventory fully before refreshing anything
• Refresh when the board is genuinely low value, not when it is merely not perfect
• Do not burn ten refreshes on Saturday morning hunting one item
• A bad purchase costs you more than a missed one — eggs you did not spend are still eggs

Weekly rhythm: farm eggs Monday through Friday, enter the weekend with a stockpile, evaluate before buying. Arriving at the shop with no eggs makes the refresh limit irrelevant.

Choose one dinosaur, raise it to level 30, and gain +1% Troop Attack per level — up to +30% at max.

Choosing your dinosaur

T-Rex, Triceratops or Ankylosaurus. All three give identical bonuses. The choice is purely cosmetic — pick the one you want to look at for thirteen weeks. You are locked to one species for the season.

Feeding it

• Pet Feed / Dino Feed — hatches the egg and pushes growth stages. This is your speed of progression.
• Pine Cones — enhance dino specialization. This is your power scaling.

Five limited-time daily tasks award Pet Feed. These are the primary progression driver for the entire system and they do not carry over. Missing a day of tasks is a permanent loss of growth. Set a reminder if you have to — this is the single easiest thing to fall behind on because it never feels urgent on any given day.

Milestones

• Level 16: unlocks an exclusive vehicle troop skin for your chosen species. One skin only.
• Level 30: +30% Troop Attack, the cap.

Everything here is season-limited. Both the attribute bonuses and the vehicle skin are removed when the season ends. That is not a reason to skip it — a 30% troop attack bonus across thirteen weeks of PvP is enormous — but it is a reason not to treat it as a permanent investment.

The shop trades Ancient Dino Eggs for rotating goods on weekends. Manual refreshes also cost eggs and become more expensive as you use them. A refresh can reveal discounted valuables, and the refresh count resets when the shop reopens on Saturday.

LastZ.GG recommendation: buy scarce exclusive-equipment materials first, then orange hero fragments. Refresh only after checking the full board; do not spend your shop currency chasing a perfect roll.

If your alliance ignores Trade Hubs, you are handing free diamonds to alliances that did not. This is the highest-value alliance objective in the season.

How they work

Trade Hubs are capturable structures. Hold one and it generates diamond tax envelopes distributed to your alliance, and unlocks an exclusive shop.

Week 1 is state-only. From week 2 the hubs open to cross-state competition, and the PvP intensity rises sharply.

The shop

Everything costs diamonds. Stock includes hero fragments, badges, plug-in chests, steel, speedups and power cores. The conversion rate from diamonds to power here is far better than any standard source, which is exactly why the diamond-saving advice in GUIDE-02 matters.

Capture strategy

• Pre-stage troops before the window opens. Marching after 11:00 means arriving to a contested hub.
• Assign roles in advance: rally leaders, reinforcement fillers, a hub manager who controls access settings.
• Rotate reinforcements so the hub is never briefly undefended — snipes happen in exactly those gaps.

The access-control meta

Alliance leadership controls who may use a captured hub, and the timing of that decision is where most of the value sits.

• First 30–60 minutes: alliance only. Your own members shop first at full availability.
• After that: open to the public. Every outside player who spends diamonds in your hub generates tax revenue for you.
• Once cross-state opens: an open hub means you are collecting tax on enemy state players' diamond spending while fighting them elsewhere on the map.

A busy hub is a profitable hub. Advertising your open hub in state chat is not a joke strategy — traffic is literally the revenue model. The most common Trade Hub mistake is not losing the fight, it is capturing a hub and then leaving it locked down all session, generating nothing.

The rule: Stegosaurus first, always

Stegosaurus rallies cost more fuel but drop Ancient Dino Eggs, which Velociraptors do not. Since your attempts are capped rather than your fuel, spending a capped attempt on the lower-value target is pure waste.

Attempt counts change after week two

Always attack the highest level your virus resistance allows. The reward curve is steep and a single tier makes a real difference over thirteen weeks.

Predator Squad data

Predator Squads scale to level 200 on the map. Kills are capped at 2 per day Monday–Saturday, 5 on Sunday.

Note that Dino Egg drops are flat across every tier — 150 regardless of level — while Fern Leaves and Scales scale steeply. If you are farming Predator Squads for eggs specifically, the lowest tier you can clear reliably is the efficient choice. If you are farming for building materials, push as high as your power allows.

Every dinosaur you kill generates Glory Points, scaled to the target's level. Every eight hours you can collect a Glory Chest.

Season Journey pass doubles every Glory Chest reward. Same 8-hour cadence becomes roughly 300 badges per chest and about 900 badges/day. Buy early so the doubling compounds.

An 8-hour cycle means three chests per day. Missing one is a full third of your daily badge income — set a phone reminder if you have to.

Alliance Season Points = combined personal glory of all members + city points.

• Personal glory accumulates from active participation in seasonal combat and events
• Cities generate points over time while occupied — and critically, accumulated city points are not lost when you lose the city. Taking a city and holding it for a day is permanently worth something.
• Glory War runs every Tuesday. Winning lets you take points directly from the enemy.

Our Alliance Duel guide covers rally mechanics and coordination that carry directly into Glory War.

Final reward brackets

During the weekly Black Market Auction, Predator Squads and Black Market Guardians actively attack Headquarters. Their attacks bypass Headquarters Guards and damage Headquarters durability directly. The Predator Squad daily reward limit rises to five while the event is active.

• Defeating a Predator Squad can reveal a Black Market Guardian.
• The team landing the final blow earns the mailed Discovery or Kill Reward.
• Defeating the Guardian rescues an injured Spinosaurus.
• Rescue-alliance members can send Scouts to shorten its recovery; up to 10 recovery gifts can be claimed per event.
• State Tasks reward all survivors, while personal ranking uses total damage dealt to transporters.
