This week’s addition to the Instant Games Collection is Metal Slug XX which came out on the PlayStation Portable, but also happens to be compatible with the Vita. SNK’s run-and-gunner will be available for download later today, after the PlayStation Network is updated.
Metal Slug XX is an updated version of Metal Slug 7. The revised version features extra content, including coop multiplayer, various minigames and DLC, so if you have somebody to play with, you should definitely play Metal Slug XX.
But that’s not all, since Plus subscribers will also be able to download Thomas Was Alone: Benjamin’s Flight level pack at a discounted price. The PSN price is $2.49, but Plus members can download it for $1.74.
