is there anyways to beat the buff guy in the gym, it seems like my melee don't do anything when i run out of ammo.
The only way to kill him is with a gun. You shouldn’t have used the bullets before facing the boss. you better start over where you got the gun and not use it until you get to the boss
You can use the stick until he kneels and then use the gun to hit his core ~(=^‥^)ノ
