How co-op works
Online co-op missions let players coordinate stealth infiltration, share ammo and intel, and tackle multi-phase vehicle bosses that demand synchronized fire and resupply. Separate versus modes offer competitive combat scenarios outside the cooperative operations.
About this game
Set ten years after Operation Snake Eater, Peace Walker follows Big Boss as he commands a private military force in Colombia amid Cold War tensions. When Costa Rican representatives arrive with intelligence about a looming armed threat, Big Boss accepts a mission that pulls him into conspiracy and confrontation. This Master Collection version updates the PSP original with improved resolution and online multiplayer support.

Stealth infiltration blends with base management and soldier recruitment. Players extract enemy troops to expand Mother Base, research weapons and equipment, and deploy resources across operations. Multi-phase boss encounters pit squads against heavily armed vehicles, rewarding teams that coordinate targeting, share limited ammunition, and time resupply drops. Missions vary from quick strikes to extended tactical operations that demand careful loadout choices.
Co-op scales mission difficulty for squad play, with communication shaping success in enemy detection and resource sharing. Players unlock gear through R&D, expand Mother Base facilities, and follow the story through codec exchanges and animated briefings. The episodic structure supports both short sessions and longer campaigns, while versus modes provide competitive alternatives after the cooperative missions conclude.

How does co-op work in Peace Walker?
Peace Walker supports online co-op for squad infiltration missions. You can team up with other players to tackle stealth operations, share intel during enemy detection, and coordinate on multi-phase boss fights that scale difficulty based on your squad size. Communication is key for timing resupply drops, sharing limited ammunition, and coordinating targeting against heavily armed vehicles.
Can I play the entire campaign in co-op?

You can run quick strikes or longer tactical operations with your squad, and the game scales mission difficulty based on whether you're playing solo or with teammates. Co-op enhances the experience especially during boss encounters that require coordinated tactics.
What's the base management system about?
You'll build and expand Mother Base by extracting enemy troops during missions and recruiting them to your private army. These soldiers contribute to R&D for unlocking new weapons and equipment, and you can deploy resources across different facilities and operations. Your base development directly affects what gear and capabilities you have available for missions.
Does this Master Collection version have PvP modes too?
Yes, in addition to the cooperative missions, Peace Walker includes versus modes as a separate competitive option. However, the main focus is on the co-op campaign and collaborative boss battles-PvP is available after you've tackled the cooperative content.
