Sony has announced via the PlayStation Blog its line-up of free games for the PlayStation Plus Instant Game Collection in June, most notably Metal Gear Solid: Ground Zeroes.
The full list of titles, which will be available from June 2nd in North America and June 3rd in Europe is: Metal Gear Solid: Ground Zeroes (PS4), Skulls of the Shogun: Bone-A-Fide Edition (PS4), Call of Juarez: Gunslinger (PS3), Cloudberry Kingdom (PS3), Futuridium (PS4 & PS Vita), and finally, Super Exploding Zoo (PS4 & PS Vita).
Given that Ground Zeroes follow-up The Phantom Pain is launching later this year, now's a very good time to play it if you haven't done so already.
It seems fans generally aren't too keen on the PS3 offerings this month so at least they're free if you have a Plus subscription. You still have time to pick up May's Plus games, details of which you can find here.
Sony's E3 press conference is set for June 15th and the platform holder may annonce plans to expand its Plus offerings then.
