Counter Strike was/is/will be a multiplayer game. The single player mode is a bad joke. Try to play the single player without cheats for a change, it will be different I tell you. I cannot tell you how to cheat there, 'cuz I myself never used cheats in CS. And if you want to really play CS, get a few friends to play on LAN, or go online. That is what CS is made for, belive me you will forget cheats in no time. The feeling to play with real living players insted of bots is worth everything

If you can't do these, fire up a server and play against bots. If you learn how to play, you will find yourself not needing cheats anymore.
Peace...
