Counter-Strike: Global Offensive (CS: GO) will expand upon the team-based action gameplay that it pioneered when it was launched 12 years ago.

Essentially a polish update to get this on the same level with regular AAA titles. Sounds and music are well done just as the models. It adds some popular community developed game modes without the need for server admins to install mods. The workshop is a great way to browse for new maps. Buy it when it is heavily discounted especially if you already own Counter-Strike: Source.
