Available to play
FortressCraft (FortCraft)
Plays Minecraft as a Team Fortress 2 mercenary, with TF2's classes, weapons and buildings running against Minecraft's world and mobs.
What it does
A two-process passthrough in which Minecraft draws the world and owns its blocks, mobs, dimensions and saves, while a locally built Team Fortress 2 bridge supplies the player, classes, weapons, projectiles, Engineer buildings, menus and HUD. The creator documents mob targeting, block breaking and explosions, and lists known gaps such as Medic healing against Minecraft mobs. It is a source preview built from the Source SDK, not a one-click installer.
How it works
Minecraft Fabric mod + Source SDK 2013 TF2 bridge exchanging state over a shared-memory protocol

Evidence limits
On 2026-10-11 the GitHub README, tags and release page were read: releases 0.3.0-0.5.1 (all 2026-10-11) add MvM-style robot raids with a wave panel and boss/Tank, a bookshelf upgrade station, a backpack shortcut for Minecraft items and creative flight; the README now documents Windows and Linux zips (Linux flagged as less tested) and the MIT LICENSE is unchanged. No independent catalogue play-test was performed.
