Stronger characters:
Create a new profile, name it MATTSOELL, and start a new game. A message
will appear to confirm correct code entry. When playing under this file,
Tex and Brutus can take more than three direct shots of the rocket
launcher without being near death. Note: "MATTSOELL" is the project
director for Bungie who made Halo. Note: You must watch the full
ending once, have all the DNA canisters, and at least one open campaign

Dumber enemies:
Create a new profile, name it SPRAGNT, and start a new game. A message will

setting, enemies will miss you more often, act stupid, and your squad will
be more intelligent and shoot and kill enemies with no instructions.

least one open campaign file for this code to activate.
Better aim:

hit things much more often. Flint's special meter will decrease slower, and

code to activate.
Higher defense:

seem to dodge projectiles. Note: You must watch the full ending once, have

activate.
Quicker death:

Cartoon mode:
Create a new profile, name it HVYMTL, and start a new game. A message will

a cartoon, with coloring book-style models, blood resembling paint, lava with
a paper feel, and different level layouts. Note: Note: You must watch the full
ending once, have all the DNA canisters, and at least one open campaign file
for this code to activate.
Tougher game:
Create a new profile, name it BRUTAL, and start a new game. A message will
appear to confirm correct code entry. This code completely beefs up the
enemy AI and seems to change their behaviors. Even under the Standard difficulty
setting they will ambush you, find a way to hunt you, and come flailing out in
order to kill you. They will take the same amount of hits, but be much harder to
put down, thus making the entire game harder. They drag themselves away when
wounded, similarly to the original previews of the game or when you fight the
Halo aliens under the Legendary difficulty setting. Note: You must watch the
full ending once, have all the DNA canisters, and at least one open campaign
file for this code to activate.
Bots in multi-player:
Start a game of Squad Deathmatch. Plug in controller two and set the A.I to
"Fire At Will". Go around and pick them up some good weapons and medkits, then
disconnect the controller. Your squad will now be facing three heavy thinking
bots in multiplayer mode.
