We were talking 2 days ago about the next Monster Hunter World extension, Iceborne, revealed during the Sony State Of Play.
To increase even more the number of players, Capcom decided to give a Free Trial of the game on PS4. That trial end of May 20th, it got three main quests, in two different worlds: Ancient Forest and the Wildspire Wastes.
You can also entirely customize your character, play with other players (from the free trial or not), and you would your save file if you would choose the buy the game.
As a reminder, the extension Monster Hunter World Iceborn will be available September 6th!
