PlayStation Plus deploys free Metal Slug XX this week
Metal Slug XX, compatible with both PSP and PS Vita, is this week's new recruit for the PlayStation Plus Instant Game Collection. PS Plus subscribers can grab SNK's run-and-gunner gratis starting tomorrow - the usual asking price is $20.

Metal Slug XX is an altered version of Metal Slug 7 on the Nintendo DS. It features additional ad-hoc co-op and mini-games on top of the core DS game. The series is known for its expressive sprites, powerful weaponry, insane boss battles and blatant disregard for bullet rationing.
