Protopet strategy
When you get up to the final boss make sure you have alot of money for ammo you might die a few times. When you get up to him take out either the the plasma coil/storm or the minitube/mega rocket and start shooting him. If he eats an ammo case strafe and dodge the missiles or whatever he shoots at you and keep firing at him. If you break the case before he eats him you either have a choice to take out the synthanoid/kilonoid and black/sheepinator and take out the other protopets. I recommend saving the synthanoids/kilonoids for later though. Oh and make sure you go to slims weapon modification shop to get upgrades for your weapons. They help cut down his health even more. And the person who submmited the 2nd floor glitch was right. You don't want to go down to the third floor. There are tanks so try to hit him with that bomb. Then keep on strafing and firing at him. Soon enough he will die. It worked for me! And please don't think it's just another boss beating tip. It really works so please try to use it
