Turtle Rock Studios has announced players on Xbox One and PC will be able to try out Evolve, the four versus one monster hunting multiplayer title, for free this weekend. The event begins on September 4th at 12:01 AM PT and for 24 hours the content of the Hunting Season One will be available to play with. On September 5th it will be Hunting Season Two that players will get to experience. If you choose to buy the game then any progress made will be retained.
If you already own Evolve on either of these platforms then you’ll get access to all the DLC throughout the entirety of the weekend. The Meteor Goliath will also be released as a free update for all players. Whether this will help boost the popularity of the game will be determined after the event.
