Portal Companion Collection
The 
Portal Companion Collection is a bundle of both main games in the Portal series available on the 
Nintendo Switch. It contains the following games:
Portal (including Portal: Still Alive)
Portal 2
It is developed by Valve, in conjunction with NVIDIA Lightspeed Studios, who previously ported 
Half-Life 2 and Portal to NVIDIA Shield (which runs on 
Android), to be the official port of both Portal games to the Switch, proving that Source games can be run on the Switch.
However, while the main parts of both games are ported, there are some notable differences. For example, in Portal 2, the PTI, including Workshop support and custom chambers, has been stripped, along with Robot Enrichment, and the menu UI (VGUI) used in Portal are based of the consoles' version (Xbox 360/PlayStation 3) of The Orange Box UI rather than Steam Deck UI, and additionally, the games also have achievements support (something which was probably rare[confirm] in Nintendo consoles, and most likely it was client-sided only[confirm] unlike X360/PS3 version and other consoles), beside from that, it appears that the port was based off the Xbox 360 version but runs on newer engine (Source 2013), as there are leftovers of Xbox's Gamerscore in the Achievements menu, and Portal 2 ARG (including Transmission Received achievement) being present. It is locked to 1080p, 60FPS while docked, and 720p, 60FPS while undocked, which is a notable improvement over the Xbox 360 and PS3 versions of the game. Other than this, the games are identical to their PC and Nvidia Shield counterparts.
However, unlike the Portal Bundle (a bundle similar to this but for PC), in the Portal Companion Collection, Portal is also bundled with Portal: Still Alive, making this the first official release of said mappack since 2008.
