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