Most of Bushido's additions are good, butdoesn't really work. Just because a player can do something, doesn't make it a trope. Otherwise, every game with projectile weapons would have "Accidental aiming Skills". Besides, that's more of a narrative trope rather than a gameplay trope.
well, yes, other FPS games are similar in that respect but i'm pointing out a particularly interesting incarnation of the trope
i mean, in most games, you don't have people waltzing blindly outside only to get nailed by a player who's not even there anymore
