The PlayStation Plus Instant Game Collection adds quite a number of high-profile games this month. Headlining the new additions is Deus Ex: Human Revolution, which will be available for members in tomorrow's PlayStation Store update.

Other noteworthy additions to Plus this month include IGF-winning adventure game Machinarium. You can also prepare for the superpowered-hijinx of Saints Row 4 with Saints Row: The Third.

Tomorrow, Plus members will also be able to get a few exclusive discounts. Portal 2 drops below $10, while new release GRID 2 will be available for 10% off.

Do note that a number of other high-profile games are leaving the service, so make sure you add them to your Download List before they leave Plus. (You'll be able to re-download them any time later, so long as you keep your membership active.) Sleeping Dogs, Ratchet & Clank: All 4 One, inFamous 2, and LittleBigPlanet 2 all leave the service this month. (It being E3 month, we wouldn't be surprised to see some major announcements for next month, however.)

Vita members will also get two full games to play: Orc Attack and visual novel Zero Escape: Virtue's Last Reward.
