MOTHERSHIP

Roll only when failure matters. Under the target succeeds; equality fails. Doubles are critical: 00 always critically succeeds, 99 always critically fails. A failed check or save gives 1 Stress; a critical failure also calls for Panic. [+] / [−] means roll twice and take the best / worst outcome. Both cancel.

Each round is about 10 seconds. Describe the threat and stakes → hear everyone’s response → resolve checks and saves → resolve damage and wounds → describe the changed situation. Usually move Close and do one thing; spend the whole round running to reach Long range. Attacks use Combat, then weapon damage on success.

Apply Damage Reduction first. Damage below AP is stopped. Damage equal to or above AP destroys armor; apply the remainder. Anti-Armor ignores and destroys armor, but not DR. At zero Health, take a Wound, roll its injury type, refill Health, then apply overflow. At Maximum Wounds, make a Death Save. Wounds & Death tables ↗

Minimum Stress starts at 2. Stress caps at 20; excess reduces the relevant Stat or Save. Rest somewhere safe and roll your lowest Save: success removes Stress equal to the ones digit, stopping at Minimum Stress; failure adds 1 Stress. Shore Leave can turn Stress into improved Saves (p. 39).

Marine Panic prompts Fear Saves from nearby friendly players. Android presence gives nearby friendly players [−] on Fear Saves. A Scientist’s failed Sanity Save adds 1 Stress to nearby friendly players. A Teamster can use [+] on one Panic Check per session.

When ambushed or shocked, a Fear Save decides who can react this round. If your table wants strict initiative, use the optional Speed Check: successes act before enemies, failures after.
