Counter-Strike: Global Offensive will receive a sizable update on Monday, according to a recent developer blog. The update will include a revised matchmaking system for Classic Competitive mode and number of bug fixes. Valve will also release two new maps for the game with the update: Monastery and Vertigo, the later seen in the above image recently tweeted by the Counter-Strike team. Valve has not specified which platforms the update pertains to, but we're guessing the Steam version is on that list.
