How the T10 Research Calculator Works
This tool tracks progress through Unit Special Training — the research branch in Last Z: Survival Shooter that unlocks Tier 10 units. It has 22 nodes spread across 246 levels, and it costs 1,488,100 research badges to max every node. Pick "Sequential Progress" and set your current level on each node, or drop your total badge count into "Custom Calculator" if you don't want to click through every node individually. Either way you get the same three numbers back: badges spent, badges remaining, and percent complete.
How Unit Special Training actually works in-game
UST sits in the Laboratory alongside the other research trees, but it behaves differently from most of them: instead of one flat unlock, it's a set of 22 separate nodes (things like troop ATK, troop DEF, training speed and march-related bonuses), each with its own level cap and its own badge cost per level. Costs are not linear — the first level of a node might cost a few hundred badges, while the last level of the same node can cost thousands. That's why a flat "badges per level" estimate is useless here and you need the full per-node, per-level table this calculator is built on. Completing every node also stacks up to 5,138,798 power, roughly 3.45 power for every badge spent across the branch.
How the badge costs were collected and verified
The badge cost for every single level of every node was cross-checked against two independent community sources: ztools.co.uk, which reports scraping the live in-game research panels directly at HQ 30, and lastzguides.com for node totals and level ranges. Author DXB KING (State 511, HQ35, T10 complete) then verified the totals against screenshots taken on our own account and a second alt account, confirming each node's per-level array sums to its published total and increases level over level with no gaps. The cost table was verified in-game on 1 August 2026.
What "Sequential" vs "Custom" mode changes
Sequential mode assumes you're researching nodes level by level in order, and it sums the exact per-level costs from the table as you tick levels up. Custom mode skips that and just takes a raw badge total you type in — useful if you already know how many badges you've spent overall (from your in-game research log) and just want a quick remaining/percentage readout without re-entering every node.
Frequently Asked Questions
Unit Special Training, often shortened to UST, is the in-game name for the research branch that unlocks Tier 10 units. It contains 22 nodes across 246 levels. Most players refer to it simply as T10 research.
Completing the full Unit Special Training branch costs 1,488,100 research badges. The final node alone costs 54,900, but almost all of the total is spent on the 21 nodes before it.
Maxing every node in the branch grants 5,138,798 power, which works out to roughly 3.45 power per badge spent across the branch.
Yes. When players talk about the badge cost of going T10, they mean the Unit Special Training branch. This calculator covers all 22 of its nodes.
Every per-level cost was cross-checked against two independent community sources — ztools.co.uk, which scrapes the live in-game research panels at HQ 30, and lastzguides.com for node totals and level ranges — then verified against screenshots taken on our own HQ35 account. Each node's per-level array is checked to sum exactly to its stated total and to increase monotonically, level over level.
Yes. Alongside the badge cost per level, the underlying data records the power gained per level for every node, so the sequential tracker can show cumulative power (5,138,798 at full completion) next to cumulative badges spent, not just one or the other.
