Sony just announced the slate of free games you'll be able to download this month as part of its PlayStation Plus program, and players shouldn’t hesitate to make these titles part of their Instant Game Collections.

Starting tomorrow is Square Enix's stellar Deus Ex: Human Revolution, a game that combines electronics-driven tactics with deep storytelling. Later in the month, you'll also gain access to several hit games, including the strategy classic Machinarium, the enjoyable action sequel Saints Row the Third, the strategic Orc Attack for PS Vita and the popular Zero Escape: Virtue's Last Reward for Vita.

Other games will unfortunately disappear from the service. Tomorrow's your last chance to download Sleeping Dogs, and next week, you can say goodbye to Closure, Ratchet & Clank All 4 One, Infamous 2 and LittleBigPlanet 2.  The PS Vita brawlers SoulCalibur: Broken Destiny and BlazBlue: Continuum Shift Extend will also get removed.

In addition, you’ll receive discounts on other games for PS Plus, including Let's Fish! Hooked On (down to $10), Portal 2 (only $9.59) and GRiD 2 (available for $53.99).
