About the Project
This is a first-person shooter built entirely in Minecraft using datapacks, custom models, and animated Java rigs—inspired by the grimdark universe of Warhammer 40K (though unofficial and non-commercial). Every asset was crafted from scratch, with no pre-existing mods—just pure vanilla mechanics pushed to their limits.
150+ hours of development
100% custom entities & weapons
No external assets—only Minecraft’s vanilla framework
A Note on Bugs & Feedback
As my first major datapack project, there may be glitches lurking in the shadows. If you encounter any, leave a comment—your reports will help purge the corruption!
"When in doubt, /reload… and pray the triggers still recognize you."
