Counter-Strike: Global Offensive is officially free-to-play on PC and Mac, and a new, smaller scale battle royale mode has been added.
Announced through counter-strike.net, the mode is called Danger Zone, and is played by 16 players at a time (this can go up to 18 if players queue as a squad of two or three). This battle royale mode revolves around a tablet that characters can use, seeing a visual representation of where the Danger Zone is closing in as the match progresses.
The tablet can also track the movements of other players and their drone deliveries, allowing you to strategically use this information to your advantage. The tablet can be upgraded to gain more detailed intel on the ever-changing Danger Zone.
