In Chapter 3 when you fight the general for the first time, run around the room to the lower left of the screen. Keep running around the little "L" shaped wall there until the general is on the outside out the "L". Then, run to the the door on the midle right side of the screen. The General will stay on bottom left of the screen and just sit there while you kill the respawning mutants that appear from the door. If you have the Meat Cannon and position yourself the correct way, tape Attack and allow the game to idle. You will gain about 200 experience points and twenty small battery packs each time you kill a mutant at that door.
