ProjectFlint
by kas
ProjectFlint is a Fabric overhaul that reworks core Minecraft gameplay, with changes to progression, technology, world generation and mob spawning.
What it does
The mod pursues broad gameplay overhauls, including in some cases full technological reworks and new progression systems. Its world generation and mob spawning mechanics are changed as well, so a new world plays differently from vanilla. The author names Vintage Story, TerraFirmaCraft, Better Wolves, GregtechCEU and real-life human history as sources of inspiration for the direction.
Fabric API is required and must be installed alongside ProjectFlint. The mod runs on client and server, so servers and every player need it. Files are published for Fabric only, for Minecraft 1.21.11, and the latest file is 0.31.19-b, dated 2026-08-16. The code is under All rights reserved and is not open source, though source code is publicly available.
