Valve had also imagined something else to provide a real killer app for VR: in addition to Half-Life, it was thought of as a Portal 3

In an interview with Geoff Keighley, the Valve team recounted the origins of the project Half-Life Alyx, a Half-Life 2 prequel that will be available in March 2020.

As we explained to you, the game will be dedicated exclusively to SteamVR compatible devices, so it will not be possible to play it without a virtual reality viewer.

However, Valve had also imagined something else to provide a real killer app for VR: in addition to Half-Life, he had thought of a Portal 3.

The idea was unfortunately discarded because the developers soon realized that moving from one portal to another would cause motion sickness, or motion sickness, in players.

For this reason, the team at the service of Gabe Newell has focused on a more traditional experience like a shooter based on mainly horizontal gameplay, though rich in puzzles and exploration, like Half-Life.
