Q: Where are the extra lifeboxes?
A: 1. After exiting the sewers on the other side, go into the first white
building alongside the path and head to the lower-left corner of the
maze and walk into the wall. You'll find one lifebox.
2. From the addams' mansion: Walk along the secret path through the
bushes on the left side of the house. Once you're inside you'll get an
additional lifebox.
Q: Give me some boss help!
A: Okay.
mcwhimpie, xybar: Basically, just make sure you have large amounts of
invisibility potions. Stay invisible to get in close and fire away with
your fully-powered up gun/whip.
mutilator troy, mr. thunderblade: same as above, but more difficult to
hit with a gun or whip; use invisibilty and homing missiles until the
boss dies.
main computer: First, destroy the bottom two lasers with invisibility and
your gun. The rest is easy; destroy the final laser port with homing
missiles and you're done.
