Counter-Strike is a modification (MOD) to the excellent game, Half-Life. It modifies the multiplayer aspects of Half-Life to bring to it a more team-oriented gameplay. Counter-Strike provides the player with an experience that a trained counter-terrorist unit or terrorist unit experiences. The MOD is team-based featuring one team playing the role of the terrorist and the other team playing the role of the counter-terrorist.

Counter-Strike is the most popular online team shooter in history, and for good reason. More than a decade on it is still the best and the most entertaining game of its type, has the best scenarios, and is the best place for gamers to really show their mouse skills.

Each side has access to different guns and equipment, as well as different abilities. Maps have different goals such as: hostage rescue, assassination, bomb defusion, Terrorist escape, etc. Weapons include the usual assortment of pistols, shotguns, assault rifles, sniper rifles, grenades, demolition devices. Each side has access to a different subset of weapons so for example only the counter-terrorist can use the M4A1, and only the terrorists can use the AK-47.

We are confident that we've created a MOD quite unlike any other. This is Counter-Strike 1.5 for Half-Life Retail (WON). Requires Half-Life Retail 1.0x or 1.1x. Not for steam. This was the last version of the Counter-Strike mod produced for Half-Life retail, until Valve switched over to the Steam network, shutting down WON. They then released Counter-Strike 1.6. You can still play multiplayer for this if you use the WON2 patch.

Google it, and you will be able to play this with other people. I did not produce this and have no claim on its copyrights. All rights go to Valve.

I just downloaded cs1.5 for steam and i installed it. I can see it fine in my steam list and when i open it, it loads the map perfectly, only thing is i cant join a CT or T team, it gives me the option to either join spectate or auto join team. Can someone please tell me how to fix this also i was wondering how do you play cs1.5 in steam online?
