Animated Taunts, oh how much fun those would be in Dirty Bomb. Although the game is fast paced, the taunts are pretty hilarious and I actually use them sometimes along with my cocky attitude whenever I kill people.
So, why not have animations to go along with them? They could be simple teabags, or the character dancing and showing off their moves.
Comment below for more suggestions, and maybe the development team will think about implementing them
