In No Guy's Sky, aliens are built from a combination of classic Doom monsters and humans, meaning that it's entirely possible to see Neil deGrasse Tyson's face pop up in-game. Much like in No Man's Sky, the mod randomly generates landscapes and creatures for the player to explore. 'I've not got around to playing No Man's Sky yet,' says modder Robert Prest in a video showcasing his mod for Doom. 'But I've based it on what I saw in the trailer.' Remarkably, the mod's creator Robert Prest claims that he has never even played No Man's Sky. The mod also contains space stations stocked with vending machines, and a well-labelled 'Center of the Universe' to discover. In the mod, entitled 'No Guy's Sky', players can visit other planets, mine resources, and communicate with aliens, amongst other things that are all possible in No Man's Sky. If you never got round to playing Hello Games' universe-exploration title No Man's Sky, now could be your chance as one dedicated modder has transformed Doom into a replica of the somewhat poorly-received game. No Guy's Sky is a mod of the classic 1993 shooter Doom.

No Man's Sky has been remade in another fan-project, courtesy this time, of modder Robert Prest.
