Atlus has released a new trailer for Metal Slug XX which is coming to Sony PSP February 23. The trailer shows some gameplay, the stages, the characters, the co-op, the modes. It’s pretty much the same Metal Slug deal again. Which isn’t a bad thing, since the Metal Slug games are great. I guess Atlus realizes their formula has been recycled and used for a while now, so the new title will be generously priced at $19.99. Enjoy the trailer!
