Welp this is interesting isn't it? I've heard very mixed opinions on ammo systems in LISA but I though that this could spice up combat a bit. Arnold and enemies with guns work with ammo how this works is that each time they shoot there's a chance the gun will run out of ammo. The chances vary based on how much the character shoots. When running out of ammo they can reload in order to regain gun based attacks or they can use their other attacks as long as it doesn't use the bullets in the guns.
