Log in as Lazarus and use Inferno as a call-sign.  A saved game
will be waiting for you which will bring you to the last level.
 
While in your cockpit hold down right-shift and type LOLIFE
to activate the cheat mode.  You will be invincible and have
unlimited weapons.  Also, you can pause the game with ALT-P
and press 1-7 to help the various pods along.
