Exciting games are in store for the members of PlayStation's subscription service, PS Plus. The streaming service for PlayStation gadgets has come out with the list of free games for the month of June earlier than usual and it includes big titles for the PS4.

A post on the PlayStation blog announced the lineup for the upcoming month, with six titles that members can avail free of charge. Out of the lineup, four titles are playable on the current generation console while the remaining two are accessible on the PS3 device. Two titles are also playable on PS Vita.

Perhaps the biggest title that would interest fans for the month of June is the inclusion of "Metal Gear Solid V: Ground Zeroes" for the PlayStation 4. The title is the prequel to the upcoming "Metal Gear Solid V: The Phantom Pain," which is scheduled for a release later in 2015.

The preview for the game read, "The nail-biting mission onto a Cuban military base follows Snake as he attempts to rescue Paz from enemy imprisonment."

According to Tech Times, not everyone was delighted when "Metal Gear Solid V: Ground Zeroes" came out in 2014 because its "demo-like nature," which could be finished in a short span of two hours, does not justify the expensive $40 price set for the title.

But that will soon change since the game, which has additional side missions to extend the gameplay, will be free in June.

Another PS4 title available in the list is the "Skulls of the Shogun: Bone-A-Fide Edition." Players can lead an army of dead samurais to complete missions in this turn-based strategy game.

"Futuridium EP Deluxe" and "Super Exploding Zoo" are both playable on the PS4 device and PS Vita. Player must protect "animal eggs in the zoo from evil aliens who want to eat said eggs" with the help of animals exploding. On the other hand, the Futuridium EP Deluxe is a throwback shooter game that has "crazy action, puzzle elements and a bumping electronic soundtrack" that makes it very exciting and fun to play with.

The Wild West arrives to PS3 devices with "Call of Suarez: Gunslinger." Players get to play as bounty hunter Silas Greaves who shoots down anyone that crosses his way.

Last but not the least, "Cloudberry Kingdom" is a 2D video game for PS3 players, which will test anyone's platform-building skills.

All the free games will be downloadable from the PS Plus service beginning June 2.
