Unlock Characters For Multiplayer Mode
To unlock characters for Multiplayer, collect DNA containers stashed throughout the levels.

Single Player Breeze
If you dont have anyone you can play with and you are forced to do this yourself, you can have a relatively easier time (and save ammo) by simply using Hawk (the Assassin) to kill one or two enemies while cloaked, then retreating to regenerate energy, then doing this over and over until you need the really heavy firepower of your AI buddies.

Bust 100%
In order to achieve 100 percent completion on a mission, you have to play on the Brutal difficulty setting. Complete all primary and secondary objectives, kill every single enemy and find the hidden DNA sequence. Also, you cant allow any of your teammates to die.

Cheatcodes
For each of the cheats listed below, enter it as your profile name when beginning in order to activate the cheat:

DEADAIM: Better Aim
ERINROBERTS: Better Defense
HVYMTL: Cartoon Mode
MATTSOELL: Tougher Characters
RAPIDFIRE: Rapid Fire Weapons
SPRAGNT: Stupid AI

Easy Attacking
Use your other characters to support you at the flanks, this will make it easy for you to attack!

Bust 100%
In order to achieve 100 percent completion on a mission, you have to play on the Brutal difficulty setting. Complete all primary and secondary objectives, kill every single enemy and find the hidden DNA sequence. Also, you cant allow any of your teammates to die.

Earning Medals
At the mission select screen, youll see four spots for medals. The first three spots are filled when you beat the mission on Standard, Hard and Brutal. The fourth is filled when you find the hidden DNA sequence. If youve completed all objectives and killed all enemies, the medal will be gold. If not, it will be silver.

Regenerating
Heres a little cheat to regenerate your teammates. If youre on your last guy, insert another three controllers into your Xbox and press start. As new players join, your teammates will be brought back to life. Now just quit out of the three games you just opened and youll go back to single player mode, but your teammates will remain.

Regeneration Glitch (Special Energy)
Regenerate special energy quickly by crouching (push in the left joystick, or as the PS2 dorks call it, Press and hold L3).
