See The Ending Sequence Before The Game

Use the -console command line cheat and start a new game. When you're on the tram (the train) keep using ur console and /impulse 101 cheat to get some weapons. Try at different times because in some places the code won't work,but get the waepons before you get to where you get off. When you have weapons and reach your destination, kill the guard just as he is putting in the code to open the TRAM door. Then kill yourself! Hit a key and you'll be on a tram traveling thru space with the mysterious man. He'll ask you if you want a job or to participate in a battle yopu can't win. It's the ending sequence!!!

Skip One Whole Level!

In the level "On a Rail," stop your rail car over the bridge in the beginning of the level. Get the battery (if needed) and jump on in! Kill a few Hag Worms and grap the ammo on the bottom. Swim over to the grate in one wall. Swim through it and get out your shotgun! As soon as you emerge, shoot the Houndeyes. Keep following the path until you reach a open room with dead grunts and a Bull Squid. You'll see one bright red Blast Door. Go through it and kill the Headcrabs and any Grunts. Ta-Da! Your Done!

Never Get Hit

To have all (except for a few big monsters) not attack you press the ~ key, then "/notarget", then enter and presto your no longer a target.

Low Friction

You can use this code to make the ground as slick as ice. Its always fun to use this code to make things a bit more interesting when you're bored. During the game press the tilde key (~) to access the console. Then type sv_friction (-999 - 9999). The default is "4". If you set this higher than 10, then you will move extremely slow, also if set lower than -3 its kinda hard to control your actions possibly resulting in health loss.(negative numbers will cause you to be "sucked" in the direction you move and the only way to stop is to hit a wall.)
