This mod will spawn the bar guy at Commerce. He will try to attack and kill you. He is a good fighter, so don't underestimate his fighting moves. He can switch fighting moves from boxing to Tae Kwon Do to Kickboxing to Boxing and over and over. If you try to attack him with a weapon, he will use the same weapon you are holding to kill you. He also has much life, so don't be afraid to run out of fun, just kill him like a cold killer!
For bugs, I haven't found any and I've tested this mod on my own computer and it works fine...
