Long loved series Serious Sam is coming later this year to both Vive and Oculus (once Touch controls arrive)
A very brazen move by Croteam going VR exclusive with such a small market available, but SS fits perfect into the world of VR, with static placement and hordes of enemies washing over you, it just works well.
With dual wielding of guns (and even chainsaws!!!) this looks to be a great one to keep an eye on.
