Work towards inclusion of VR for 0.9.4 is currently underway on the beta branch. Right now you're able to play the entire game in VR as everything is being developed!
Here's a video showcasing the current state of VR as of today:

What's supported?
The game uses OpenVR so this means any HMD supported by SteamVR should work!
Just as a side note, because of the VR integration the game now uses DX11 instead of DX9. The game will fallback to DX9 if your GPU doesn't support DX11 however.
How do I try it out?
To try out VR mode, first make sure you're on the beta branch. You can access it by right clicking the game in your library, going to properties, the beta tab on the window that opens and then select the "beta" option from the dropdown.
You'll likely now want to restart Steam. When you load it back up you'll now see BallisticNG in your VR list and if you right click it again, you'll see a "Launch BallisticNG in Steam VR Mode" option.
For those of you looking to run the game without Steam, you can also launch the game in VR mode using the new -vr argument. There is a .bat file next to the game's executable which will launch the game with this argument without you needing to setup a shortcut. Just make sure you've got SteamVR installed and running.
I found a bug!
