If you are thinking about buying Metal Gear Solid: Peace Walker in Master Collection Vol. 2 to play with friends, the main answer is simple: multiplayer is present in the 2026 re-release. CO-OPS supports 2 to 4 players, while VERSUS OPS goes up to 6. The point that requires attention is compatibility: Konami says there is no general crossplay between platforms, but Nintendo confirms an important exception, because Nintendo Switch and Nintendo Switch 2 can play online together.
Master Collection Vol. 2 was released on August 27, 2026 for Nintendo Switch 2, Nintendo Switch, PlayStation 5, Xbox Series X|S, and Steam. Within the collection, Peace Walker is the game that offers online multiplayer. Metal Gear Solid 4: Guns of the Patriots is not part of that six-player figure.
Does Peace Walker co-op work in the 2026 re-release?
Yes, in the sense of official support. Konami released the new version of Peace Walker with online CO-OPS and VERSUS OPS, and the company’s own online manual explains how to create and search for matches. The PlayStation, Xbox, Nintendo, and Steam stores also continue to list multiplayer features for the version released in August 2026.
That is not the same as promising full matchmaking queues or a perfect connection at any time. The documentation confirms that the feature exists and is available in the product; player population, latency, and how easy it is to find strangers can vary by platform, region, and time of day.
How many players can join CO-OPS and VERSUS OPS?
CO-OPS: 2 to 4 players
The cooperative mode is for 2 to 4 people. The official manual explains that missions whose participant limit is at least two can be played in CO-OPS. One player acts as HOST, opens the mission, and recruits the others; anyone who wants to join can search for a host through the CO-OPS menu.
This limit matters because some stores summarize Peace Walker as an online game for up to six people. Six is the overall multiplayer ceiling, not the size of the cooperative group. For team-based missions, treat four players as the maximum.
VERSUS OPS: up to 6 players
VERSUS OPS is the competitive mode and supports up to six participants. The re-release manual describes four rule sets: Deathmatch, Team Deathmatch, Capture Mission, and Base Mission. Here too, one person creates the session as HOST and the other participants search for and join the match.
So the correct reading is: co-op for 2 to 4; competitive play for up to 6. If you saw “2-6 players” in a store listing, that represents the product’s multiplayer range as a whole and does not turn CO-OPS into a six-player cooperative mode.
Does Peace Walker have crossplay between PS5, Xbox, PC, and Nintendo?
No. Konami explicitly states that Peace Walker online play does not offer crossplay. In practice, there is no official basis for expecting matches between PlayStation 5 and Xbox Series X|S, between PS5 and Steam, between Xbox and Steam, or between any of those platforms and Nintendo consoles.
When putting a group together before buying, treat PlayStation, Xbox, Steam, and Nintendo as separate ecosystems. The only compatibility between different console versions documented by the official stores is online communication between Nintendo Switch and Nintendo Switch 2.
Then why can Switch and Switch 2 play together if Konami says “no crossplay”?
Because the two statements address different levels of compatibility. Konami’s wording rules out general crossplay between ecosystems. Nintendo, meanwhile, details compatibility within its own console family: the official Peace Walker page says online play is possible between Nintendo Switch and Nintendo Switch 2 systems.
For that reason, the safest interpretation is “no crossplay between competing platforms, with Switch-Switch 2 interoperability confirmed by Nintendo.” Whether you call that connection crossplay or cross-generation compatibility changes the terminology, but not what matters for a purchase: a person on Switch can play online with another person on Switch 2.
Who can play with whom on each platform?
PlayStation 5 with PlayStation 5
Yes. The PlayStation Store lists the PS5 version with online play for up to six people and requires PlayStation Plus for multiplayer. For CO-OPS, the limit remains four players; six is the overall multiplayer ceiling for competitive play.
PS5 with Xbox, Steam, or Nintendo does not have official crossplay support.
Xbox Series X with Xbox Series S
Yes. The release is treated as a single Xbox Series X|S platform, and the Microsoft store lists online co-op for 2 to 4 and online multiplayer for 2 to 6. Console multiplayer requires an Xbox Game Pass plan that includes online play, according to the store itself.
Xbox Series X|S with PS5, Steam, or Nintendo does not have official crossplay.
Steam with Steam
Yes. The Steam page identifies both Online Co-op and Online PvP in the Peace Walker version. At the same time, Konami says there is no crossplay, so a PC group should be made up of players using the Steam version, without counting on a connection to consoles.
Nintendo Switch with Nintendo Switch
Yes. Nintendo lists online play for 2 to 6 and local communication for 2 to 6 for the product. CO-OPS remains limited to 2-4 by the mode’s rules, while VERSUS OPS can reach six.
Nintendo Switch Online is required to use online play.
Nintendo Switch 2 with Nintendo Switch 2
Yes, with the same player-count rules. The Switch 2 version lists one player on the same console, 2 to 6 through local communication, and 2 to 6 online. Again, the six-player figure applies to multiplayer overall; cooperative play is capped at four.
Nintendo Switch with Nintendo Switch 2
Yes, online. This is the combination that often creates confusion around “no crossplay.” Nintendo itself says online play is possible between Nintendo Switch and Nintendo Switch 2 systems. Therefore, friends on those two generations can form online matches together in Peace Walker.
Nintendo’s page also lists local communication for 2 to 6 on each version, but the explicit note about interoperability between Switch and Switch 2 is phrased for online play. Without equally clear confirmation about local communication between the two versions, it is better not to assume every local scenario works the same way.
How does CO-OPS matchmaking work?
Peace Walker keeps a host-based structure. For a mission that is eligible for cooperative play, one player selects the HOST option and opens recruitment. The manual shows invitation options such as Domestic, Private, and Global. Anyone who wants to join uses SEARCH HOST, sets the search criteria, and enters a session that is found.
That is different from imagining a modern system in which the game always assembles a complete group automatically. Host search and recruitment do exist, but the experience of finding strangers depends on there being open sessions in that ecosystem at that moment.
For playing with friends, the purchasing rule matters more than matchmaking: before each person buys the game, confirm that everyone will be on the same compatible ecosystem. If one person is on PS5 and another on PC, for example, it is not enough for both to own Peace Walker; they will not be able to enter the same session. If one person is on Switch and another on Switch 2, Nintendo confirms that online connectivity between the two is supported.
What about local multiplayer?
On Nintendo consoles, local communication is available for 2 to 6 players, according to the official pages for the Switch and Switch 2 versions. Konami also states that Peace Walker supports play through local communication on those systems.
On PS5, Xbox Series X|S, and Steam, the official pages consulted focus on online multiplayer. There is no equivalent indication of a local multiplayer mode for several players on the same console; local play on a single machine is listed as one player.
What you need before buying to play as a group
The first point is the platform. Everyone on PS5 can play together; Series X and Series S form the same Xbox ecosystem; Steam players stay on PC; Switch and Switch 2 have online compatibility with each other. Between those groups, there is no general crossplay.
The second point is team size. If the goal is to play through missions in CO-OPS, plan for a group of no more than four people. If the goal is VERSUS OPS, the ceiling rises to six.
The third point is online services. On PS5, the store requires PlayStation Plus. On Xbox Series X|S, Microsoft requires a Game Pass subscription that includes online multiplayer. On Nintendo Switch and Switch 2, online play requires Nintendo Switch Online. On Steam, the game page offers Online Co-op and Online PvP without indicating an additional subscription equivalent to those on consoles.
The answer for deciding whether to buy
Peace Walker in Master Collection Vol. 2 preserves the multiplayer side that sets the game apart: CO-OPS for 2 to 4 people and VERSUS OPS for up to 6. The 2026 re-release has official online support and uses host-based session creation and search.
The important caveat is crossplay. Do not buy expecting PS5, Xbox, and PC to mix in the same team, because Konami says crossplay is not supported. The practical exception is Nintendo Switch with Nintendo Switch 2: Nintendo confirms online play between the two systems. If the group already knows where each person will play, this rule resolves the main question before purchase.
