Transforms Bonelab avatars into Minos Prime and Sisyphus Prime with authentic voice lines and adjusted strength, speed, and weight, letting players embody two ULTRAKILL bosses in VR. Created by drasticobra as a mods release for Windows PCVR, the package pairs high-fidelity models with rigging and texture work tuned for Bonelab's physics interactions. It targets ULTRAKILL fans and Bonelab players who want boss-tier avatars for sandbox combat and spectacle.

What kind of mod places ULTRAKILL bosses inside Bonelab?

The mod reproduces two specific Prime Souls from ULTRAKILL, offering high-fidelity 3D models of Minos Prime and Sisyphus Prime that plug into Bonelab's avatar system. The package includes model, textures, and rigging tuned for VR, not a total conversion. The focus is on embodiment, letting players switch into those exact characters inside Bonelab's existing levels and gameplay loops.

Does the mod change how you play in Bonelab?

The avatars carry tailored stats that adjust strength, speed, and weight, so the player's physical interactions change compared with standard avatars. Custom gameplay attributes reflect a boss-tier feel by altering movement and impact in physics-driven encounters. These changes affect sandbox combat and melee interactions, making avatar choice influence how you approach fights in Bonelab.

What does the mod look and sound like in VR?

Models use optimized textures and rigging for smooth performance in VR, and the mod includes custom voice lines and auditory cues drawn from ULTRAKILL material. Audio integration gives each avatar distinct vocal feedback for actions, which reinforces the characters' presence during close-quarters combat and when using Bonelab's physics objects.

How do installation and compatibility behave for PCVR players?

Installation follows common mod.io and Bonelab procedures: place files in the Mods folder or use the in-game browser. The mod targets Windows PCVR and notes compatibility with standard VR hardware supported by Bonelab, so setup fits existing Bonelab mod workflows and the developer's distribution path.

In summary, a theatrical avatar mod for fans who want boss-level presence

The Prime Souls package suits players who want to embody iconic ULTRAKILL bosses inside Bonelab, especially those who value voice integration and physics-aware rigging. Expect a persona-focused addition rather than a gameplay overhaul; players seeking entirely new mechanics or level content should note this remains an avatar mod that changes how you feel and interact in the game world.
