Most of us know and love the multiple game-of-the-year title Half-Life. But some of us suck at it. I've beaten the game on the "medium" level of difficulty, but not the hard. So I guess it is safe to say that I am a pretty good player, as I have beaten just a little more than half the game on hard. Well, enough about me, let's talk about your own skill. If you think that you are the worst Half-Life player on earth, You can visit this plage first: The Beginner Tips.
If you think that you are not horrible at the game, but still have lots of room to improve, then visit this page: Medium Player Tips.
Finally, if you think you are a fairly good Half-Life player, I suggest that you look over this page: Advanced Player Tips.
If you have beaten the game on all levels of difficulty and always come in first in multiplayer, be gone! We don't need such good people here!
