Mechwarrior 3 Cheats

Beat Instant Action and you get Unlimited Ammo and Invincibility but
these cheats don't work in the campaign

Select the chassis Daishi. Un-quip everything (including
Double Heat Sinks, etc.). Put 1 Er Laser (L) Clan in the head,
2 Er Laser (L) Clan in the center torso, 9 Er Laser (L) Clan and
1 Er Laser (M) Clan in the left torso, 2 Heavy laser (M) Clan
and 1 Laser (S) in the right torso, 2 jump jets in each leg, and
in the right/left arm you can put anything (ammunition, equipment,
etc.). If you stay in the water on The Road to Madre, you will
not be shut down as easily from heat.
