Robert Prest is an aspiring modder, who presented his talents recently to the world by developing No Man’s Sky as a Doom mod. He needed three weeks to do his work, which he based solely on the trailer.
An even more impressive fact is that he basically built it from scratch, borrowing only certain codes from another game. In fact, those codes are also his work. He used them for another project – Day Z based Doom mod called DoomZ.
The Doom version of No Man’s Sky brings you into a world of interplanetary travel, in which you are moving toward the center of galaxy, fighting procedurally generated creatures. You can download it from here.
