Onward is a tactical shooter specifically thought for VR sets - i suppose HTC Vive sets. At the moment it is on early alpha.
From the looks of it, i get the vibe of VBS 2.
This is the second DEV vlog where it explains the general concept of control usage. It's from Dec 15.
This is the latest gameplay vid
this is the very first time i get hyped for a VR game... can it be a killer app?
