Counter-strike!!!

Cheats and hacks are fine, warez is not. I will note, however, that if I had developed such a thing, unless I found something better, I'd keep it a secret rather than give it out so that it ends up patched.

Some time back, Asus released drivers for one of their video cards that had a built in wall hack (and earned my eternal boycott in doing so); your best bet may be to find those or a derivative or copycat work.

Really, though, the best solution is to just play on unsecured servers with all the other cheaters. It levels the playing field. Personally, it annoys me alot when the people I'm playing against are obviously cheating and I am not cheating. I mean, that's the reason that you play on secure servers, to test genuine skill against genuine skill; not to get picked off from a mile away as you emerge from behind hard wall to behind a peirceable barrier.
