Hello!, Today i was playing the game, and, because i can, i start to kill everyone, so, the point is, i was using the gatling laser and then i realise that no waste ammo! just put another core, i have 42 cores and 500 ammo, fire, make 500 shots, and put a new core, and still have 42. So that's all. Hope it helps!

oh! i forguet to say, i have 42 cores, 4 of then are already used (on power armors) and using one right now, maybe it helps!
