De officiële site van Valve over Half-Life: Counter-Strike is on-line. Op deze site geven ze een beschrijving van het spel en zetten ze de features nog even op een rijtje. Ook is er een forum waar je je mening, opmerkingen, suggesties, etc. over CS kwijt kunt.Half-Life: Counter-Strike is the ultimate multiplayer gaming experience, combining all the elements of the Half-Life online universe with new single and multiplayer content. At the heart of this package is Counter-Strike, the number one played online action game built as an add-on for Half-Life, the PC CD-ROM named Game of the Year by over 50 publications worldwide.

Counter-Strike is team-based, and casts players in the role of terrorist or counter-terrorist. Each team has access to different ammunition and equipment, and each player has unique attributes and the ability to upgrade their gear as they successfully complete each mission. A growing number of missions are available, each having specific goals, such as rescuing a hostage or eliminating key enemy structures.

Since it's initial Beta release in Fall 1999, Counter-Strike has taken multiplayer gaming by storm to become the number one played online action game – surpassing all commercial and non-commercial titles in its class!

Op de site staan wel een paar kleine foutjes, zoals de verkeerde hoeveelheid RAM vereist voor CS (ze hebben waarschijnlijk gewoon de sys reqs van HL zelf overgenomen...) en de verkeerde Beta 1 release datum van CS .
