Seen moments ago at Cologne's Gamescom, this trailer for upcoming Playstation Portable title Metal Gear Solid Peace Walker explains how the game will support up to four player cooperative play.

The must play PSP Games every gamer will enjoy.

It feels like the PlayStation Portable doesn't get the love that it deserves, so here are the best PSP games if you're picking one up for the first time.
some really good games on that list. some of my favorites (not on the list) are Metal Slug XX, ultimate Ghosts & Goblins, Gradius Collection, Motorstorm Arctic Edge and Ratchet & Clank: Size Matters.
I get that The Warriors is technically a PS2 game ported over, but damn it's amazing on the PSP
Few of my favs Off the top. Midnight club 3,GTA Stories liberty/Vice,god of war and locoRoco

VGChartz's Issa Maki: "Even to fans, the thought that a T-rated game could rank as the greatest is virtually unthinkable; how could the best Metal Gear possibly be a handheld title on a system less powerful than a PlayStation 2? Because it had to be – necessity is the mother of invention. Not only is this a full-fledged Metal Gear, the fresh spin on the gameplay draws from several sources outside of its wheelhouse. Peace Walker somehow manages to be less like its predecessor, Portable Ops, and more akin to Metal Gear Solid V. What boggles the mind is that it would be over five years before The Phantom Pain would release, an entire generation later."
This isnt the 1st.
Simply incredible! It's crazy to think that this gorgeous game is running on a PSP.
