Cyborgs should receive a pop-up when they attempt to suicide.

[Superlagg]

This isn't going to stop someone who doesn't want to play a borg that round, and really there's no real way to force someone to play when they don't want to. Instead of an unhappy camper mushing their head, you'd just get a bunch of inactive or pissy borgs.

Just have the suiciding borg just plop their brain out on the floor, preferably with a note attached. Or leave the brain in, eject the ghost, and raffle off their seat to another dead person.
