 | 2 | BAND_CHECK "3 random + reroll" [ASSUMED] | **All unlocked bands are shown.** In co-op, players pick **one at a time in a random order** shown on the left ("以随机顺序进行策略轮选"). Each co-op player may **skip once**. The step lasts 50 s; on timeout the band is 华法琳. **Duplicates are allowed:** the official illustration shows 2 teammates' picks still un-greyed in the grid.

That is its original tile unless it was moved off it (a 突袭 jump, 乌尔比安's anchor). No ally may deploy on that tile ("倒地干员所在地块视为可部署，但所有我方单位在此处的部署行为将被阻止"). One knocked out on another piece's initial position goes back to its own ("若干员被击倒的位置为其他干员或召唤物的初始位置，则在被击倒后，尝试返回其自身的初始位置").<br>Deploy effects do not fire during prep placement. Battle speed is forced to **2×**. | VERIFIED |
 | 4.3 | leaked/timeout | When `maxPlayTime` ends, the battle stops. Every enemy not killed (still alive, or reached the goal) is "未击倒" and feeds 联防/LP. [ASSUMED] `maxPlayTime` is **game-time** seconds, so the client at 2× shows it ticking twice as fast. Last spawns land at 15/38/73 s against limits of 45/55/115 s, which leaves the time needed to kill walkers. | VERIFIED + ASSUMED unit |
 | 3 | solo prep 300 s | 下半 solo has **no timer** on prep or 机变 ("休整期及机变阶段没有时间限制…24小时内随时返回"). Treat `normalPhaseTime` 300 and `specialPhaseTime` 150 as an optional "timed solo" setting. | VERIFIED |
 | 4.4 | 联防 partner rule "fewest leaks" | Meaningless, because helpers are perfect by definition. There are **at most 2 helpers**: "所有防卫成功的玩家（最多2名）". Default choice: highest LP, then seat index [ASSUMED]. 1 helper uses `escaped_single` (8 units); 2 helpers use `escaped_multi` (20). | VERIFIED cap |
