The two games in the series, Portal and its sequel Portal 2, will be packaged as the "Portal: Companion Collection".
The collection is set to release
later this year and will cost US$20 upon release.
This announcement is a surprising one, since the Nintendo Switch is a direct competitor to Valve's Steam Deck console, which is set to release two weeks from now.
The first game in the Portal series was released almost a decade and a half ago in October 2007 as part of the Orange Box collection, which also contained Team Fortress 2 and Half Life 2: Episode Two.
The sequel, Portal 2, was released three and a half years later, in April 2011. The release of Portal 2 marked the start of a period of few game releases from Valve.
