Currently re-editing this one to allow four players; I'm not sure if I should revert the Engineers back to GoodGuy and enable all players to control them (would make certain triggers easier to fuck around with), or divide them between two houses. Currently leaning towards the 'GoodGuy' option to be honest, at least that way it's also playable with two or three players.
Edit:
Well fucking forget giving everyone control, a recent test proves that it just isn't workable when players aren't communicating.
