It’s Doomception. A modder has made it possible to play Doom while playing Doom.

The arcade machine mod plops in a console that you can play both Doom and Wolfenstein 3D on.

This isn’t the first time we’ve seen this kind of mod for Doom – there was also the Mortal Kombat 2 arcade machine from a couple of years ago.

Doom is expected for release on PS4, Xbox One, and PC in Spring 2016. But you don’t have to wait that long to get another look at it.

Bethesda will be at QuakeCon with more Doom and Fallout 4 next week, so we’ll keep an eye out for any interesting tidbits.
