两个合成一个。十个变五个，五个变两个 —— 最后剩下的那一辆， 要扛住整波敌潮。10 章 50 关 380 波，每一波都是一次新的赌注。
Merge two into one. Ten become five, five become two — and whatever is left has to survive the whole wave. 10 chapters, 50 stages, 380 waves, and every wave is a new bet.
单局 3-8 分钟。10 秒一次合成决策，每一波之间抽三张强化选一张 —— 每一步都在赌这一波守不守得住。
3-8 minute runs. One merge decision every 10 seconds, and one upgrade out of three between waves — every step is a bet on whether this wave holds.
两个同级单位合成一个更强的。合成树就是改装树 —— 往上合会分叉成不同流派，走哪条线由你定。
Combine two units of the same tier into a stronger one. The merge tree is the upgrade tree: merging branches into different builds, and you pick the line.
每一波之间抽三张强化，选一张立刻生效。强化不重复、会叠层，越到后期越要取舍。
Draw three upgrades between waves and keep one — it takes effect immediately. Upgrades stack, so late waves are all about trade-offs.
59 种敌人各有各的打法，从废土街区一路打到沙暴封锁。死了不冤 —— 每一局都能说清楚自己输在哪。
59 enemy types that each fight differently, from Ruined Blocks to Sandstorm Lockdown. No unfair losses: you can always point at what went wrong.
