The battle royale craze pushes ahead, as Scavengers Studio's battle royale game, Darwin Project, re-launched this week on Xbox One as a free-to-play game. The game originally launched on Xbox One in the Game Preview program as a paid title before this week's business model switch to entirely free to play. The changes were announced on Xbox Wire.

Those who already paid money are getting compensated, thankfully. The next time you log in you should see Founder's Pack content in your inventory, including a lot of cosmetic items. This includes two "legendary" sets of items that contain a shirt, pants, armor, helmet, boots, three axes, three bows, and a "full jumpsuit collection." You also get 10 "fan gifts," which include other items you can use to customise your look and weapons.
