There is a free trial for Monster Hunter World on the Ps4.
The trial, which runs until May 20, allows you to play the opening section of Capcom’s game, allowing you to gain a taste ahead of the new expansion, which releases later this year.
All eight assignments up to Hunter Rank 4/3* are available as part of the free trial and If you meet certain conditions, you can also go on optional quests, investigations, event quests and challenge quests before hitting the latter.
Both the Ancient Forest and Wildspire Waste are included within the trial and you can even carry over your save data should you wish to continue.
If you happen to have Xbox Games Pass, then you can download the full game there instead, allowing you to play without limits.
