You can add the following strings into [CS] section of Iron_3D.ini file
from game directory:
String Effect
-------------------------------------------------------------------------------
INVULNERABILITY=1 Hero invulnerability (no effect for bot's!)
FULL_RESEARCH_TREE=1 Allow to use any bot's components without research
WINDOW_MODE=1 Runs game into window
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!).
