Sony's PlayStation Plus Instant Game Collection promotion continues to move on, as the company has announced which free games will be available for the month of March.

Leading the pack is Tomb Raider, one of 2013's best adventure games, for PlayStation 3. Players will guide a young Lara Croft through a death-defying adventure, as she fights her way through a tropical paradise filled with danger.

Also being given away to PS Plus members during the month of March is the puzzle platforming game Thomas Was Alone and the survivor horror game Lone Survivor: Director's Cut.

Meanwhile, on PS Vita, two games will be offered. The action-packed Unit 13 has players taking on dangerous missions with a military tactical team, while Monster Hunter: Freedom Unite allows them to team up with others to bring down nasty behemoths.

Finally, on the PlayStation 4, Housemarque has prepared a new edition of Dead Nation, co-titled Apocalypse Edition, which features streaming support, improved visuals and controls, and, surprise, more zombies.
