@kisak-valve Thank you for referencing my issue! I'm glad it's not something unique.
The game isn't working even on latest Proton-Experimental.
steam-213120.log
With the new steam client and proton experimental as discussed in https://github.com/ValveSoftware/Proton/issues/753#issuecomment-954401990 the game now launches and played correctly for the first few scenes in a quick test.
As commented in https://github.com/ValveSoftware/Proton/issues/3232#issuecomment-954799448, the problem has been fixed.
Finally closing the issue 😄
Compatibility Report
System Information
I confirm:
steam-213120.log
Symptoms
Game does not launch after hitting PLAY (it installs Directx and Visual C++ 2010 automatically).
Since it's predecessor (War for Cybertron) uses NVIDIA Physx, I tried to install that through protontricks, but that doesn't seem to do much.
Reproduction
Install the game, set the Proton version to 4.11-8 and hit PLAY.
