The free games coming to PlayStation Plus for June 2015 have been announced today by Sony via the PlayStation Blog. Included in the games is Metal Gear Solid V: Ground Zeroes and a mix of other games that total four PS4 titles, two PS Vita titles, and two PS3 titles.
Metal Gear Solid V: Ground Zeroes (PS4)
A visually stunning chapter in a long-running, deeply complex series. This nail-biting mission onto a Cuban military base follows Snake as he attempts to rescue Paz from enemy imprisonment.

Skulls of the Shogun: Bone-A-Fide Edition (PS4)
This turn-based strategy game turned a lot of undead heads with its story of a Samurai Afterlife. Build an army of the undead, battle your opponents, and regain your honor.

Super Exploding Zoo (PS Vita | PS4)
Players must defend all the precious animal eggs in the zoo from evil aliens who want to eat said eggs. How do you defend these tasty treats? With a herd of explosive animals, obviously.

Futuridium EP Deluxe (PS Vita | PS4)
A psychedelic, retro-inspired shooter with crazy action, puzzle elements, and a bumping electronic soundtrack. May or may not induce random dance parties.

Call of Juarez: Gunslinger (PS3)
This first-person shooter celebrates the wild west in a big, bloody way. Take down anyone unlucky enough to cross bounty hunter Silas Greaves.

Cloudberry Kingdom (PS3)
The dev team behind this insane 2D platformer spent 2 years building an AI that could build a near-infinite number of levels for any difficulty. It looks totally bananacakes. Good luck with that!
