These guys have the skinny not only on the mission objectives, but places to hit for bonuses and places to outright avoid.
Watch Your Ammo Supply
Yeah, those short-range missiles are pretty impressive, but save them for larger targets. You've got a really limited supply. The best plan is minimum firepower for maximum result.
Dodge, Cover And Run
Don't walk into the line of fire, I learned the hard way. Use buildings and other structures for cover as often as possible. When you see those guided missiles heading your way, run like hell, and as erratically as possible. Sometimes you can shake them off and save yourself a world of hurt.
Smash Those Buildings
Inside many key structures you'll find health packs and other goodies. This can mean the difference between a critical failure and mission success. Also, many of the buildings are spawn points for tanks and other nasties. Destroy the buildings and you'll have fewer opponents to worry about.
Keep Cool
Heat is a factor that must be monitored. Certain weapons generate heat as you fire them, so once your weapon overheats it won't function anymore, which takes you right out of the battle. So you can use natural settings to get rid of heat, like jumping into a river.
Fit The 'Mech To The Mission
Prior to each mission you can configure your 'Mech's weapons through a wide variety of options. But the really cool feature is the ability to do mid-mission weapon upgrades. Remember those smashed buildings? If you find a weapons facility building, bust it open. Inside will be bonuses such as a brand new Heavy Gauss rifle that can be installed right there.
Avoid PPC projectile
To easily avoid a PPC projectile when playing on Xbox Live, choose a mech that has jump jets. While the enemy is charging up their PPC, activate your jump jets. Once they fire, release the jump jets and the PPC will fly over you as you fall to the ground. This can be very effective against Mad Cats.
