Cool MP game idea: Jailbreak
There would be 2 teams. Each team has a prison with a force field or door and whenever anyone is killed by any means including suicide, he respawns in the enemy team's prison where he stays for 1 minute (default) before being executed. After players are executed, they return to the game. The players lose their force powers and weapons when in prison but get them back by escaping or being executed. There is a big button outside the prison just next to the door that can be pressed to open the door to free the inmates (escape). When someone is in prison, a countdown timer appears on their monitor before being executed.
Being killed: 1 point to enemy team
Being executed: 3 points to enemy team
Rescuing prisoners: 5 points + 3 per prisoner to your team
Friendly fire off
