HL2 & HL2 VR - Comic Book Mod Update V1.1
ko-fi.com
If you're looking for a completely new way to play Half-Life 2 VR, the Borderlands-like Comic Book Mod is really well made and really changes up the feel of the game. There is also a version of the mod that is compatible with standard HL2 so if you don't have a VR headset, you can still benefit from the mod.
This is a really neat idea, though the backgrounds should probably be more "painterly" and less "poster edges" for better contrast with the characters.
