HalfLife: CounterStrike is one of the most unusual PC game releases in months. And if you don’t have the exceptional HalfLife, the new retail edition of CounterStrike is a chance to get a standalone version of this outstanding multiplayer mod. The retail package also includes standalone versions of other multiplayer mods and game modes that normally require HalfLife, the best of which are also available free off the Internet: Team Fortress Classic, Opposing Force Multiplayer, Firearms, Redemption, Ricochet, and Wanted. CounterStrike itself is a superb game that fully deserves top billing in this release.
