damn dude, ive been looking around multiple threads, and in each one, you were there, bashing the ideas and adding comments like go play bf2...
you might surrender when you know you're outnumbered, and youve got no chance to win. not everyone would do it ofcourse since my guess is most of them will want to try to take as many with them into death as they can ^^
on the other hand, others might surrender, you could use the use button on them to capture them or something, and they'd 'die' and respawn.. you could get points for capturing enemies maybe.
IRL people surrendered, i think it might be another thing that could immerse you into this game more, if done well.
stop bashing truman
