Sure, concept art is nice and all, but for all we know the previously-mentioned and untitled game never even saw any of its assets converted into in-game objects. Screenshots, on the other hand, indicate that a game was at least developed enough to be running on a game engine of some sort. Some Factor 5-developed screens leaked alongside the concept art, this time for a game called “Virus.” What do you make of it from the screenshots below? Or do you think these could be mockups as well, and not actually taken from a game engine at all?
