Mech Warrior 3
Overheating is more of an issue than in any previous MechWarrior games. When you modify your loadouts, don't add more energy weapons than you can cool effectively. Those machine guns don't look like much, but they can keep tearing at an enemy while you cool down from that laser volley you just fired.
When battling enemy heavy mechs, send in whatever lance mates you have first while you concentrate heavy fire on the enemy mechs' legs. Use the zoom feature for those accurate long-range attacks.
Easy Head Shots:
Salvage a "Clan Targeting Computer" and equip it on your mech. Then target a mech's head and fire a large pulse for a one hit head shot kill.
Blow off one leg of a mech. Since a mech's legs are much weaker then the torso, it makes killing enemy mechs much easier.
Disable Heat Death On an Overheating Mech:
Pick a mech that overheats when using an alpha strike. As soon as you perform the alpha strike, press the "F" key to use your coolant. If you timed it correctly, you should receive a "Heat Death Disabled" message.
