ZeniMax files a trademark for a Doom cheat code that unlocks everything, raising hopes of a new entry in the series

Bethesda and id Software parent Zenimax Media has trademarked the classic Doom cheat 'IDKFA', adding fuel to rumors that a new game in the landmark FPS series will be revealed imminently.

The trademark, which was originally filed back in January, refers to the cheat for Doom and Doom 2 that gave players all keys, weapons, and full ammo. There's some uncertainty around precisely what words the cheat stands for, whether it's 'id Keys Full Ammo', 'id Keys Full Arsenal', or some other formulation.
