you Can use fist like a weapon in the game it not useless.
about enemies and fighting.this model just was a test and i don't use it to my game I will use ghost or zombies.
also I said that its just 40% and (without level designing this was just 5% of my level I have about 20 inside building levels and the outside is 15 times larger than that you have seen.
about weapons you saw just three weapon but I have knife,ax,some kine of old knife that people used in 18 century,dynamite maybe chainsaw ,...
But I'm agree with you and I will smooth the hand model.
sorry for my bad English:D
