High On Life's talking Gatlians crash DOOM Eternal: swap mods to hear Kenny, Gus and Sweezy, while G3 grunts trash-talk you.
Kenny and the Gatlians landed in the wrong game.
Talking guns. Every gun comes with both of its mods unlocked. Press Weapon Mod Swap (F, or D-pad Up on a controller) to flip a gun between its DOOM mod and its Gatlian, and the gun speaks in its real High On Life voice:
The HUD shows each mod by its new name. The Gatlians use DOOM's gun models (High On Life's models can't be loaded into DOOM's engine) and fire like the mod they replace.
"Wrong game." Every run opens with Kenny realising this definitely isn't Blim City.
G3 Cartel and bounties. DOOM's soldiers and zombies talk like G3 grunts and Merks. The Marauder sounds like Krubis and the Doom Hunter like Garmantuous.
Horde Mode. Kenny calls out new waves.
Single player, in the campaign and Horde Mode.
Your games, your voices. On first start the mashup reads every line from your own High On Life install and builds an official DOOM Eternal mod on your PC (about 15 seconds). Then DOOM Eternal's official mod Sandbox opens with it. Nothing from either game is in the download.
Needs: DOOM Eternal (Xbox app / Game Pass or Steam) and High On Life.
