Hint: Killing the launching opponents:
Whenever you encounter the types of opponents thatlaunch things at you, shoot at their head. Whatever they are shootingat you will also be hit, as if they were targeted. Just keep aimingat their head and they will eventually be killed. Note: This willonly work on one person at a time.
Hint: Shotgun:
When you are in the warp ahead level, get up to thepart where it says "Self Destruct". You will turn, ablue blinking light will appear. Shoot it and you will get a shotgun.
