Valve has announced Operation Vanguard, a new way of playing and accessing content for Counter-Strike: Global Offensive.
This is an access pass that lets you play a minimum of two missions per week, with two campaigns bundled in. There are also option campaigns to take additional weekly missions from around the world. Completing all the missions in a single campaign earns you challenge stars, allowing you to upgrade your Operation Vanguard Challenge Coin. There will also be a competitive scorecard and a friends leaderboard.
Outside of this, Arms Race has been updated with maps from Demolition mode, as well as a new ruleset.
For access from now until February 10, you can purchase an Operation Vanguard Season Pass here.
