Counter-Strike is something of a legend in the PC gaming world, a 1999 Half-Life mod that was bought out by Valve and is one of the pioneering titles in the modern, tactical combat shooter genre. Its 2004 sequel, Counter-Strike: Source, arguably perfected the game, and while some veterans still claim version 1.6 of the original mod was when the series was at its peak, what most players can agree on is that Counter-Strike is as good as it’s going to get.
Love this game I highly recommend it. Only 15$
