The sheer number of Doom mods available is bewildering. No other game has been manipulated and transformed as much as this seminal and genre-defining first person shooter. But now, you can finally play this masterpiece…inside the masterpiece. Thanks to YouTuber and modder TheZombieKiler, you can now approach a crude arcade cabinet, activate it, and play Doom inside a level of Doom. You can even find yourself and put a bullet in your own head…while you are playing Doom inside Doom. The grandfather theory has just met it’s match.
