Evil boss body:
Successfully complete the game during single player campaign mode.

Hint: Play as Ragnarok:
Go to Team Last Man Standing (TLMS). Set the mission to Rush Hour, and before entering a Mech, look at the names. Find the Mech named Ragnarok. This mech has a cannon that will fire three very strong rockets that can cause massive destruction. This seems to be the only level where you can play as Ragnarok. Note: You must have two players to do this.

Hint: Use Staradder in multi-player mode:
Go to Destruction and choose On The Rocks. It will be in the middle rock.

Hint: Defeating the Unfinished Skull Mech:
First, keep hitting it in the head with your lasers. A VTOL will constantly drop supplies if you happen to be hit by the Skull Mech's weapons. When you get the top layer off, Nurohack the Mech, then fire mortar rounds into its head. Watch out for its pulse lasers from long range and Napalm Cannon from short range.

Hint: Defeating Spider Mech:
Use your pulse lasers on the coverings on its legs when it gets close, and use your missiles when it jumps back. When it charges at you, just run backwards; if you run to the side it will knock you over with its front claws and hit you with the plasma cannon when you are down. Keep blasting at its legs and picking up Natalia's salvage and you should kill it without trouble.

At one point in the game, you will encounter a Spider Mech. Its tactics will be to charge at you, bash at you with its front claws knocking you down, then firing a plasma beam in a sweeping motion before jumping back. One method of defeating it is to use your Jump Jets when it charges at you. If done correctly, you will land on its back. Once there, use your Jump Jets in tiny bursts to stay on while destroying the plating on its legs. The cannons are recommended for this. If possible, get off its back to the side for better aim. With luck you should be able to destroy all the plates on one side. After a short amount of time, the spider will jump back. There is a chance you will get hit. If this happens, despite the large amount of damage taken you can simply run for the nearest health power-up. If the spider charges before you get a chance, Jump Jet to its back and slide off in the direction of the health power-up. After collecting it, repeat the process. The spider should soon be down. Note: This strategy can only be used if you did not switch mechs when you had an option to do so.

Hint: Easy kills:
To kill any mech or tank without getting hit, move back and forth and cycle your weapons, firing one round per cycle. If you this while moving back and forth you will dodge their attacks while killing them.

Hint: Heavy Assault Mech specials:
To do the special, you must have all upgrades for your Mech. When this is done, a message about maximum power will appear. This special can kill most Mechs in one hit. However, you can only use this special once before you lose all of your power-ups and overheat all the way. Note: You can use this special as many times as desired in the level, as long you get all of the power-ups.

Glitch: Surfing Skullbot's eye beams:
Jump jet and land on Skull Bot's eye lasers. After you have cracked his head open like an egg, you can manage to surf towards him. You will take damage, but this will get you into a good location to hack.

Glitch: Have thirteen people in a room at a time:
Set the public and private numbers at 11 and 1, then invite someone. Once that person comes in, change the public number of people to 12. It will now show that you can have thirteen people in the room. Note: This may sometimes glitch the game.
