Defeat all the bosses and other robots on each of the fun levels. Collect more ammo when you run out of ammo and more health when your health is low. Each of the levels bosses drop a key that will open the door.
Shoot or stab any enemy robots you come across while exploring the levels looking for the bosses to kill. Pick up the orb the bosses drop to open the door to get to the next level.
