PS Plus reminder: Thomas Was Alone & Unit 13 free tomorrow for PS3 and Vita

Following tomorrow's PlayStation Store update, PS Plus members should be able to download two more games for free: Thomas Was Alone and Unit 13

Thomas Was Alone is described as a "charming" puzzle platformer in which you must guide a group of sentient rectangles through a series of environments, combining their skills to reach the end of the level. In the most simplest of ways it showcases the camaraderie of artificial intelligence depicted as various shapes. Thomas Was Alone will be available for free on PS3 as well as on Vita.

In addition to Thomas Was Alone, Vita owners will also be getting Unit 13 for free. This is a third-person mission-based shooter that challenges you to complete specified objectives. There are a total of 36 tactical missions and 9 high value target battles.

Thomas Was Alone and Unit 13 join Lone Survivor: Director's CutTomb Raider, and Dead Nation: Apocalypse Edition as March's free PlayStation Plus offerings. Looking ahead, Vita owners will receive Monster Hunter: Freedom Unite.
