Companion Fever

A roleplaying game for 3-5 players, 1.5-2.5 hours.
Period: Pre-/Early WW II
Place: the USS Invincible, a sneaky entomology research ship, in the pacific theater. (There's RL backstore here.) In trouble.
Words used:
Entomology - part of the setting, there will also be an entomology die that is that round's resistance against the escaped "bug". Ties in to the Lead Scientist and the Marine Colonel.
Accuser: Every character (of the up-to-5 pre-defined, character-sheet-less characters) has an accuser. Every character has f*cked up in some way, and is trying to shift the blame. The accuser sits to your right, the one you accuse sits to your left. Who accuses who is pre-defined.
Invincible: part of the setting, and there's an "invincible" die that indicates that round's efforts against the damaged and run-aground vessel. Ties in to the Captain and the Chief Engineer
Companion: part of the setting (companionway), and the die that indicates the information gathering and disinformation amongst the ship companions by one of the characters. Ties in to the Secret Serviceman
Rules restrictions:
1. No charsheet + pre-defined. This is one-evening play, everyone just starts with a character job title (Captain, Marine Colonel, Chief Engineer, Lead Scientist, Secret Serviceman) and a secret f*ck-up.
2. Possibly the 'three dice' rule as well (it's been inspirational, anyway).
A game of shifting blame on a ship that's likely to be doomed!
Comments welcome!
