Things just got seriously real. The iconic original Serious Sam is now available in VR on Steam Early Access and is currently 20% off until the 25th of October. The older Serious Sam titles are also on sale at a whopping 90% off if you want the non-VR experience.

Serious Sam VR promises to be everything the original game was, all inside your virtual reality headset. Fight masses of aliens and experience the missions that made Captain Stone the legend that he is today.

Currently Serious Sam VR is only supported by HTC Vive, however support for Oculus Rift is on the horizon. Head to the Steam page for full information about what’s available in the early access, and when the developers Croteam expect to have a full release.
