With the Epic store discount, currently costs £18, so gave this a try last night.
Definitely looks good. Ran it with Vulkan with all settings maxed out. Limited my frame rate to 60 and it seemed to be using virtually no resources.
Unfortunately, as a game, left me rather unwhelmed. Nicer looking version of Left4Dead very much summarises it. Yet somehow, didn't give me that same horror feel that I had from L4D. Not sure why, just felt a little sterile, so I requested a refund (apparently Epic will give a refund if you play less than 2 hours).
