Once you install the game go into the directory of which you installed it using Windows Explorer, and find the document called ca.ini. Scroll down until you find the word Cheats in brackets. Find "InfiniteAmmo", and put 100 in place of the 0. Do this to Invulnerability. Start the game and when you play you will have Invulnerability and Infinite Ammo.
