The newest map in PlayerUnknown’s Battlegrounds, which is now being called Codename: Savage, is going to be revealed in a few short days with the map’s first private alpha test, developer PUBG Corp. announced today.

Unlike the two existing PUBG maps, which are both 8 km by 8 km, Savage will be the game’s first 4 km by 4 km map, creating the conditions for a much more intense and fast-paced game. Little else has been revealed about the map, outside of a few screenshots that make it look like it’s set in a jungle.
