With end of the month in sight, Sony has announced the next batch of free games coming for PlayStation Plus members. May will offer up the usual total of six games spread across PS4, PS3, and Vita. Thanks to Cross-Buy, you'll get up to three games on each platform.

As always, the most notably of the bunch come on PS4. With Detroit: Become Human's release approaching, developer Quantic Dream's previous game, Beyond: Two Souls, will be available for free. This was originally developed for PS3 before later being ported to PS4. Alongside it, Ubisoft's gorgeous platformer Rayman Legends will be playable for free.
