Metal Slug: Double X -- the upgraded, multiplayer-capable PSP remix of the Nintendo DS title Metal Slug 7 -- is rounding the corner to its UMD-exclusive release February 23 on PSP. Apart from adding a new coat of paint, Double X adds support an ad-hoc two-player multiplayer mode, 70 missions and a kitchen sink full of blood and bullets. What? You don't believe the game has a hearty dose of hot lead? Allow us (and Atlus) to prove it with the brand new trailer above. Also, never doubt us again!
