What's the Hell equivalent of Inception? Hellception? DOOOOOOOOOOM? Either way, it's the latest DOOM remade inside the original DOOM.
As the months have gone on, id has made SnapMap increasingly powerful. But it's certainly not at the point where we can expect to see total conversions or even full recreations of campaigns.
So, if you can't remake the original DOOM inside new DOOM — why not remake the new DOOM inside old DOOM?
The whole thing was put together using the advanced Doom, Hexen and Heretic editor, Doombuilder. What's intriguing is how they got weapons from the new DOOM in there as well, including the pistol's secondary attack and the effect on the crosshair.
It apparently took around a fortnight or so to put together. They haven't said whether they'll recreate all of the new DOOM's levels in the aging engine, as remarkably cool as that would be.
Here's hoping the whole game gets remade though — it'd be a hell of a lot of fun exploring those larger levels in the classic DOOM style.
