The original Doom is still popular after more than 20 years, and mods continue to be made for the id Software classic. However a new mod has moved the old game into the present, crossing the pixelated look with the physics and game play of No Man's Sky.

Created by Robert Prest of DoomZ, the mod is totally randomized as No Man's Sky, using the game's mining and flying between planets as the main premise. However, landing on a planet will have you running into Doom-style monsters and even monsters with the heads of Hello Games boss Sean Murray and starman Neil DeGrasse Tyson.

"Everything is randomly generated from an array, including the scenery, sky, floor, plans and aliens etc.," Prest said in his blog. "There is plenty more that can be added relatively simply, and due to the flipbook style randomisation on the creatures, each addition makes exponentially more creatures and possible planets, but I didn’t want to spend too long on this before releasing. You can mod it to put in your own faces etc if anyone wants to do that."

He said it took about three weeks to create, although that was because of feature creep. He had the basics down in three days.

If you want to play it, you need the actual Doom2.wad file. His blog gives a detailed explanation of how to install it and play it.  It should be entertaining for a while, at least.
