So I would make this myself, but I have to renew my LIVE first, so I'm just going to throw this out for whoever's up to it. If you've played an Assassin's Creed game, either Brotherhood or Revelations, you're most likely familiar with the tower concept. Sneak in, kill the captain, burn the tower. 3 phases. One team attacks an urban setting, maybe with objective alarms off, so the defenders will have to be on their toes the whole time, maybe set up territories for phase 2 with a fake captain (Coneman?) that has to be captured. (Assassinated), then the defense has to guard the tower. Now the problem is finding a way up the tower. Maybe another roof to jump from? But then you arm a bomb, creating the explosion (fire) to destroy the tower. Who wants to try it?
