Level select:
Start a new game and enter !EVAH! as a case-sensitive
name.

Invincibility:
Start a new game and enter B4K42 as a case-sensitive
name. The "God mode" selection will now be unlocked
at the options screen when the game is paused.

All bonuses:
Start a new game and enter 105770Y2 as a case-sensitive
name. Note: The code contains the number "zero" and
not a capital letter "o". All character biographies,
vehicle specifications, FMV sequences, and concept artwork will
be unlocked.

Multiple codes:
Start a new game and enter more than one code together
to activate each of them simultaneously. For example, enter B4K42105770Y2
as a case-sensitive name.


Hint: Jet mode:
The weapons in Jet mode are considerably less effective
that the weapons in Walker mode. Couple this with the fact that
Jet mode does not allow the Shield to generate. Only use Jet mode
when you need to blow something up or kill a Fighter (or any other
air units such as bombers, landers, etc.) in the air. Stay on
your side of the battle, as it will be nice to have a helping
hand when things get rough. Try not to use all your energy while
in Jet mode; when you land you will have no shield. Repair Pads
are your friends -- use them.
