Slayercraft

Become the Slayer inside Minecraft Java, with a twelve-weapon DOOM Eternal arsenal, weapon mods, physical projectiles and explosions that interact with mobs and blocks.

Version 1

• Slayer mode, weapon selector and a virtual arsenal that preserves your normal inventory.
• Combat Shotgun, Super Shotgun, Heavy Cannon, Plasma Rifle, Rocket Launcher, Ballista, Chaingun, BFG, Unmaykr, Chainsaw, Crucible and Sentinel Hammer.
• Aim/mod controls, ammo and cooldown feedback, a DOOM-inspired HUD using original imagery imported locally, and selected original weapon sounds.
• Basic idle, movement, jump, landing and weapon presentation. Third-person walking and hand placement still need polish.

Solo only. Windows x64; Minecraft Java 1.21.1 runs in a separate Fabric instance. Own Minecraft Java and an installed Steam copy of DOOM Eternal. Setup prepares the runtimes and imports game assets locally. Sign into your own Microsoft account through official Prism Launcher when prompted.

Press G for Slayer mode, R for the weapon selector, V to cycle weapons, B for weapon mods, left click to fire and right click to aim or select an alternate action. Use a new Minecraft world for the first playthrough: explosions can destroy blocks.
