Do these hand actions include "The Finger" cause i'd like that one
anyway, in all seriousness, Hand gestures are great for close range tactics, but as has already been mentioned, you need LOS on the player. I suggested in another thread that maybe we should be able to make it possible for an enemy to 'tap' into communications from the other team, if this was included, hand signals would become a vital part of the game. VoIP would be a nice option as well, i find it easier to press a button and talk that stand around and find buttons (maybe even an 'automatic mic activation' would be nice. It transmits when the volume gets to a certain height)
Just a few things to concider i suppose
