OMG I am so glad I found it. This is just perfect. It needs to be in the game as melee weapon for heavy. Group of enemies and you hit them with first and for double BONK! hit them with second. Enemies flying around. It is a strike!
Alt attack. Heavy is holding it in his hand and smashing plp around. / he can have a small bag for ball and smash plp with it as in Big Lebowski These Men Are Cowards Scene
