7. Metal Gear Solid: Portable Ops Only a Psycho Mantis couldn't appreciate the sophistication stealth-action gameplay that Portable Ops dishes out exclusively on PSP. Totally original from the ground up, the game does more than port over the console series. Creative recruitment mechanics take advantage of Wi-Fi hot-spots, letting you draft soldiers into Naked Snake's espionage ring. Additionally, robust online play complements an intriguing single-player story. Don't let this one sneak by you.
