Portal: Companion Collection brings both core Portal games to the Nintendo Switch for the first time. The edition will be released this year!
Nintendo and Valve talked about the creation of the Switch version during a Nintendo Direct that took place a couple of days ago. While Portal 2 has previously been released on consoles, the series has never made it to the Nintendo handheld. The collection includes all the single-player features for both games, as well as Portal 2's split-screen co-op mode. You can play on a local network or the Internet.
The only missing link might be the level creation tool added to Portal 2 as part of the Perpetual Testing Initiative DLC. However, the players already have a lot to do.
