How to defeat the last boss
Okay this might be a bit stupid but it will work it may take more than one go and it saves you amo
1. On the first floor when the protopet eats the amo box (let him eat it) he will shoot out smaller protopets while he is doing that get your wrench and go up to him when you go to him you will be under him
2. When you are under him BEAT THE HELL OUT OF HIM
3. On the second floor it might be a bit harder but if you need help pull out the sythenoids and the mini/mega turrret gun and pull the best gun out
