Another Left 4 Dead project – codenamed Hot Dog – was also dropped alongside a fantasy RPG project (called RPG), a voxel-based game called A.R.T.I., and SimTrek which was a VR game in development by part of the Kerbal Space Program team. Laidlaw previously revealed the story planned for this game or Half-Life 2: Episode 3 in a thinly veiled blog post.Įlsewhere Left 4 Dead 3 was briefly in development, as an open world game set in Morocco, but deemed unworkable because of Source 2’s slow development. This becomes a bit of a running theme through Valve’s 2010’s.įurther projects were Shooter, a Half-Life themed VR shooter that would have been a part of The Lab, which was Valve’s VR demo showcase for SteamVR, and Borealis, another Half-Life VR project that was led by writer Marc Laidlaw, set on the titular time-travelling ship Borealis as it jumps back and forth between time periods like the Seven Hour War.
The game was ultimately cancelled because the development of Source 2 engine wasn’t finished.
