: They both now have their SteamOS icon.Croteam have recently released both Serious Sam VR: The First Encounter [ Steam Link ] & Serious Sam VR: The Second Encounter [ Steam Link ] on Steam. They both use their new Fusion engine which comes with Linux support, Vulkan and 64bit.While neither of them have a SteamOS icon, they do both have Linux support thanks to the new Fusion engine. SteamVR for Linux is currently in Beta, so it's likely once Linux support is ready enough to be classed as stable by Valve, then it's likely both games will get the SteamOS icon.They both require a VR headset, but you're able to play with keyboard and mouse if the motion controllers aren't your thing.I won't be giving either game any thoughts, as the HTC Vive is far out reach for me financially and neither Valve or HTC are able to provide GOL with a unit to test with. Valve specifically said they were unable to and HTC haven't replied to any requests about it. I will, one day, grab a VR headset when they come down in price.
