lvl 89, died cuz of my battery. best combos ive found are drunkern stock and grip,. chaos bullets, bird friend, the mag that makes more bullets, and bee trigger(any full auto works)
this does have drawbacks, such as the slime fight almost crashing my chromebook cuz u shoot 1-20 bullets per shot and the slime stores them which causes massive lag. you do kill all other bosses in 3-5 secs. hope you use this and enjoy the game.
