The PlayStation blog just announced the PlayStation Plus lineup for March, and it's a heavy hitter to be sure. To start off, Spec Ops: The Line, one game I haven't shut up about since E3 2012, is free for PlayStation Plus members and discounted at $39.99 for regular members. If you're a PS+ member and you've starved your life by not playing this game, correct this detriment, as soon as it becomes available.
Also for free this month includes Joe Danger 2, The Cave, Tekken 6, and Disagaea 3: Absence of Detention for the Vita.
The free games start dropping in on March 5th, and several PlayStation Plus games will be dropping out starting that date as well. In other words, log into the PSN today and make sure you have everything available for the Instant Game Collection that you want.
