Since this is the "concept discussion board" now, here's a game concept that came to my mind when playing a noobish custom map recently that was absolutely stuffed with adrenaline...
Unreal PAC MAN!
Set four high level bots up in a team against the player, name'em Inky, Winky, Pinky and...and... I just can't remember how the fourth ghost was called in PacMan... with everyone at 1 health, shieldguns only and only the player able to pick up adrenaline. Out of boredom I created a custom adrenaline pickup that uses the skyball mesh and the classic *wonka, wonka* PacMan noise as pickup sound, as well as a simple Bot.Controller check so it can not be picked up by artificially controlled players. Pretty sick. Experts, try instagib
