In other PlayStation news, the free PS Plus games for May 2018 were announced just recently. They are Beyond: Two Souls and Rayman Legends on PS4, Eat Them and Risen 3: Titan Lords on PS3, and Furmins and King Oddball for PS Vita. If you haven't already done so, it's not too late to still claim April's free PS Plus games. Those include Mad Max and Trackmania Turbo on PS4. Adding them to your library will allow you to continue playing for as long as you're a Plus member. They'll be available to grab until Tuesday, May 1, when this new slate of games will replace it.
