In the game, press '~' then type the case sensitive word God(1) including the brackets.
In-game you can press '~' and enter the following string
after the 'Omen' prompt to get full invulnerability:
Looks like the programming language? Yeah - this is trick
for the internal game scripting system. But please note
that this code must be re-entered periodically because the
game doesn't store previous mode while map block change
(block changing can be determined if your HDD reads something
heavy and the game slowdowns for a while, or just see what you
now is not invlunerable and your health value is decreasing).
Hopefully you do not have to re-enter this long code - you can
just bring console ('~' key) and then press Up-arrow key to
get previous command form history.
Other codes (entered the same way):

Begin game play as Max, then hold [Fire] and
press [Equip Up] four times. A message will
confirm correct code entry.
Make use of Sniper mode as Kurt. An enemy taken out
from afar is an enemy you don't have to worry about
If concerned about ammo as Max, switch to the main
pistol it won't run out. Save the Uzis for rougher times.
Dr. Hawkins requires an unorthodox approach. Save often
and try everything; you'll stumble upon the answer eventually.
When facing the first boss as Kurt, zoom in and look for
those blue globes. There are four in the middle and two
orbiting the ship.
