If you latch onto a building or wall with your claw and aim behind you, you will shoot backwards!! It's like using a turret with feet and jumpjets!

When you get to the level where you have to take down the comms tower use the demo charges and put them in front of the tower (where the enemy mech is patrolling) and keep them there until the mech walks into them and blows up taking the tower with it(IMPORTANT: you may need to plant the explosives more than once so keep repeating the process until the mech is destroyed)

First get in a battle armor and well simple use the jumb jets to get close and hack in.

For those people who can't defeate the big spider, just hit it on the legs with everything you got.

Just a quick hint for those new to the game, you may have already been told about the 'Pilot Bomb', however, don't rely on it as it's not all it's cracked up to be, and to do destroy a Mech will take 6 or 7 attempts.
