Colombia, 1970. Naked Snake wakes in a FOX unit prison camp, betrayed by the very soldiers he trained. Portable Ops is the first canonical Metal Gear Solid entry built for the PSP, bridging Snake Eater and the later Patriot storyline by showing how FOXHOUND came to exist. The core loop marries the series' stealth-and-infiltration DNA with a squad-recruitment system: Snake can drag unconscious enemies back to his truck, converting them into playable operatives with their own skills.
