E3 is around the corner and since the PlayStation team will be pretty busy showing games on the show floor and preparing a bombastic presentation, they are already presenting the titles that will be added to the Instant Game Collection. On Tuesday, June 11th, when the PlayStation Store updates, Uncharted 3: Drake’s Deception, XCOM: Enemy Unknown and LittleBigPlanet Karting will be available for free on PlayStation Plus.
As the PlayStation blog post indicates, Uncharted 3 will include the single-player campaign and the free-to-play multiplayer. On the other hand, XCOM: Enemy Unknown and LittleBigPlanet Karting will represent the full retail versions.
