You can add the following strings into [CS] section of Iron_3D.ini file from game directory:

Cheat Code - Granted Wish

INVULNERABILITY=1 - Hero Invulnerability
FULL_RESEARCH_TREE=1 - Use Any Bot's Components Without Research
WINDOW_MODE=1 - Run Game in a Window

Note: Also you can change 'ImmortalHero = 0' to 'ImmortalHero = 1' in the Behavior.ini file (located in the game directory too) to make Hero's ammo unlimited (weapon still heat normally. no effect for bot's!).
