Valve comes with new Portal content in response to the release of the Steam Deck. Aperture Desk Job is an interactive tutorial that explains how the Steam Deck works. It takes place in the Portal universe and the ‘game’ was also developed by Valve.
The Steam page for Aperture Desk Job also shows that the same humorous tone as in previous Portal games is present in this title. Unlike Aperture Hand Lab, this is a product of Valve itself, which may also mean that Portal writers Jay Pinkerton and Eric Wolpaw wrote the lyrics for this title. Valve emphasizes that this is not Portal 3.
Aperture Desk Job is supposed to show players the various features that the Steam Deck offers. However, the title will also be available for Windows and users will be able to try it out with a controller. That will soon also apply to SteamOS 3; Valve will release it at the same time as the Steam Deck. That should already be available, but the download page still serves version 2 of SteamOS.
Portal and Portal 2 are first-person puzzle games set in the same universe as Half-Life. The company behind the testing facilities in Portal, Aperture Science, is a competitor of Black Mesa. References to Aperture Science can be found at the end of Half-Life 2: Episode 2 and Aperture director Cave Johnson talks about Black Mesa in Portal 2. For example, more about how the two game series fit together can be found on the timeline of the Half-Life Wiki.
