Zombie Siege — 30 Waves of Coordinated Chaos
Updated 7 Aug 2026 · 2 min readZombie Siege is one of those events that looks chaotic the first time you do it and actually makes a lot of sense once you understand the structure. It's a 30-wave alliance defense event — everyone in your alliance defends against zombie waves together, and the coordination between members determines how far you get.
The main reward most people care about is Golden Wrenches. Hit 2 million points and you get 13 of them. If your alliance is even reasonably active, this should be achievable most weeks.
How It's Scheduled
Only R4 and R5 leadership can schedule Zombie Siege. It runs on Monday or Tuesday only — most alliances prefer Monday because it syncs nicely with Alliance Duel timing. The event ends when all 30 waves are complete or all alliance bases are eliminated.
If your alliance leadership never schedules it, ask them to. A lot of smaller alliances miss this event simply because nobody remembers to set it up.
War Frenzy — The Key Mechanic
War Frenzy is what separates alliances that clear 30 waves from alliances that struggle at wave 15. When War Frenzy is active, all alliance members deal significantly more damage. The timing of when your R5 activates it matters a lot.
The general rule is to save War Frenzy for the harder waves — don't burn it on the early zombie waves that you can clear without it. Your R5 or R4 should be calling when to activate it in alliance chat. If they're not, ask them to.
Watch alliance chat and watch the event map. When you see a member struggling, send reinforcements immediately. A base that falls early costs the whole alliance points.
Reinforcements
When another alliance member's base is getting overwhelmed, you can send reinforcement troops to help them. This is one of the most important coordination elements in Zombie Siege.
A base that survives wave 30 with help earns everyone more rewards. Don't just sit and watch your own base — check on your alliance mates, especially the smaller accounts that might get overrun by wave 18 or so.
Scoring and Rewards
Personal rewards are based on your individual score — how much damage you dealt and how many waves you contributed to defending. Alliance rewards depend on collective performance.
The key milestone most players care about is 2 million points for 13 Golden Wrenches. Wrenches are used for vehicle modifications, which is why Zombie Siege matters even for players who think vehicle upgrades are boring.
Alliance-wide rewards arrive Wednesday after the server reset. Make sure your alliance actually completes the event before then.
