Work in progress. Ultrakill Eternal is very very much a work in progress, the state it is in as of writing this is barely functional. Expect a whole lot of more playable updates in the future!
V1 in Hell puts ULTRAKILL's V1 into DOOM Eternal's campaign. It needs both games, and everything from ULTRAKILL is read from your own copy.
V1's arm and guns on screen. The Piercer revolver, Core Eject shotgun, Jackhammer, Attractor nailgun, Sawblade launcher, Electric railcannon and Freezeframe rocket launcher replace the Slayer's hands, with recoil, sway and weapon switches.
V1's own weapons in DOOM. The revolver, its charged Piercer shot, the coin ricochet and the Jackhammer work by ULTRAKILL's rules and kill DOOM's demons. The other guns show and sound like V1's but still fire like DOOM's (for now).
V1's movement. Dash, slide, ground slam, slam jump, slam storage, wall jumps and super slide jumps, tuned from ULTRAKILL's own numbers and scaled to DOOM.
ULTRAKILL's style meter and stamina bars inside DOOM, from Destructive all the way to SSShitstorm.
V1's real sounds replace DOOM's gunfire. DOOM's own soundtrack still plays.
Every weapon from the start of each level. Hold X for V1's arsenal menu.
Controls: Space jump / wall jump, Left Shift dash, Left Ctrl slide or slam, X arsenal, G coin. Everything else is DOOM's own.
Single player. Nothing in DOOM's or ULTRAKILL's folders is changed.
