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.

System requirements:
Pentium 1000MHz, 64MB VIDEO, 256Mb RAM

How to start:
in the \ Program Files \ CS USB departing lcs.bat

Note:
Some maps do not work properly, I do not know exactly why. To resolve the problem, you have the. Wad files (see below) and insert load. But you can of course add your own maps, as in the normal CS
