Just throwing this out there. What if at the end of the round the players get unlimited ammo for a bazooka and a 30 second extended timer. This way the surviving players can have a chance at beating those last big boats that you can't manage to take down, as well as earn some more money. There's probably something you guys will argue against this and I just want to let you know I'm completely open to criticism. Let me know what you guys think.
Not really my thing, if their are more than 2 people alive at the end of the round then they probably deserve the draw. There is no need to keep fighting and I would prefer to just end it in a draw.
It's actually not a bad idea I've got to admit. It makes sense the winners get to choose the room they want to before anyone else, but they should something more for surviving or winning the round.
