Wolfram (AKA: Wolfenstein 3D Remake) is a modern HD remade edition of the classic DOS game Wolfenstein 3D, which was developed by John Carmack from id Software in 1992, and treated as the first game work of First Person Shooter (certainly, as early as 1973, the Maze War born in NASA‘s PDS-1 computer is the only real originator). It was made by Chain Studios from Russia using the Volatile3D II game engine in 2012, released for free.
