PlayerUnknown's Battlegrounds (PUBG) wasn't the first battle royale game to exist, but it certainly was the one that put the genre on the map. PUBG has been surrounded by success since its early access in March. The game has sold over 20 million copies worldwide, and it's in the number one spot on Steam's most-played games list. Veteran titles like Dota 2 and CS:GO don't come close to putting up the kind of numbers like PUBG did. In Valve News Network's latest video, the Youtuber analyzed the last ten CS:GO patches, and he found many references to a survival mode. The references include adrenaline shots, compound bows, Mk 2 grenades, medic kits, parachutes, drones, fist-to-fist combat, beacons, a new survival island map, and many battle royale related content. Although it's too soon to tell, but it looks like Valve has bitten the bullet and might implement a battle royale mode into CS:GO to attract more players.
