Unlimited health, ammo.
Welcome recruit, to the elite international special forces. In order to become the intruder, you first need to complete the Combat Training program. Engage in DM or TDM matches in 5 different maps and complete missions. Unlock new equipment, weapons, upgrades, and medals. Deep gameplay mechanics and awesomely designed graphics make this game a top notch shooter. This game has really intense graphics so you might want to turn of HQ particles, decals and anti-aliasing (you can do this from the menu).
To play intruder combat training use WADS to control your character, the mouse to aim & left-click to fire/shoot. Play the in-game tutorial to learn how to switch weapons and make tactical shots. Good luck!
