12 players in a deathmatch who can freeze the entire game whenever they want, to be used in the heat of battle to automatically lock on to body parts of other people (it makes no difference where you hit them) or their weapons (which cannot be hit by anything). When they've made their choice, the game proceeds normally with one player shooting at another player, and they wait for someone else to freeze the game for everyone (which will indoubtably happen about 2 seconds later).
This can not and will not happen.
