Counter-Strike: Global Offensive

Counter-Strike: Global Offensive (2012) is the latest game of the Counter-Strike franchise, running on the Source engine. The game contains the well known Hostage and Defuse scenarios and has several new game modes not included in its predecessors, including Deathmatch, Demolition and Arms Race. New weapons have also added: Molotov grenades, Decoy grenades, and a taser melee weapon, the Zeus x27.

The game introduces a new kind of lighting to Source, cascading shadow maps. These cast super-sharp dynamic shadows across an entire map. There apparently are plans to backport many Source 2 features to CSGO, and eventually port CSGO to Source 2.
