Counter-Strike: Condition Zero - Deleted Scenes (PC/ENG/RePack)
This is a Portable version of Counter Strike (the game would have to know everyone). I have found somewhere on the net and even here yet. You can drag this version on a USB stick and then play the way on any PC. Bots and things like that everything is already integrated. As far as I know this version even via LAN play habs have not yet been tested.
