Portal 2 is Valve's physics puzzle adventure. Its co-operative campaign is separate from the single-player story, with two robots tackling dedicated test chambers using portal guns, switches and carefully timed movements.
Exactly two players in co-op
The campaign is built for two players. On Steam, both online and shared/split-screen co-op are listed. The Nintendo Switch edition of Portal 2 also supports local split-screen, wireless multiplayer and online play.

Official listings do not establish native multiplayer compatibility between the current Steam and Switch editions. Do not assume owning different editions guarantees a shared lobby. Refer to Valve's English Steam listing for PC features.
