Mechwarrior 3: Pirate's Moon Cheats

If you are playing in Instant Action mode, choose the
water terrain (the Road to…). There is a bridge not far from
the starting location. Go to the bridge and hide under it. The
enemy Mech AI will have trouble understanding this tactic. They
will almost never come into the water to get you. They will often
sit on bridge while you peek out from below and blow them to pieces.
If done correctly, you can take out ten to fifteen waves (thirty
to fourty Mechs) before you take significant damage. Since you
are in the water most of the time, remember to take lots of lasers.
they work well in the water and heat should not be a problem.
