tHE STUFF THAT ARE -DEV STUFF ARE TRUE BUT THATS NOT HOW U REALLY DO IT..
I ALREADY TRIED THAT STUFF AND IT DID NOT WORK, THIS IS HOW U REALLY DO IT.
FIRST U HAVE TO GO TO START, AND THEN CLICK ON RUN.. THEN TYPE THIS IN c:sierragunmangunman then hit space once and type exe space -dev space -console then click ok and it will go on gunman automaticly and u will see the word console!!
Dont click on it..
Theres no piont of clicking on it, just go to load game or what u want to play in gunman. then on the left of the number one button there will be a button that looks like this ~ and ` on the bottom of ~.
Click on that button and a black space with words in it will take up half of your game space, if u want to have god mode on just type in god..
lolz if u type god in u wont get hurt at all only ur armor will but not ur health!! pretty cool huh?? and noclip.. noclip is another cheat this cheat will make u go through walls and fly in the sky. Impulse 101 make sure u always put a capital i.. and make sure u hit one space before u type in 101..
For some strange reason Impulse 101 will not work sometimes so if it does not work i have nothing to say. but it will always work when u start a new game!!
