Climb Tartarus together.
A fan-made project turning Persona 3 FES into online co-op. Your friends in the party, one tower, and the game's own world, characters and battles, built on a from-scratch PC port.
Coming soon. No release date. Requires your own copy of Persona 3 FES.
Persona 3 FES came out on the PlayStation 2 in 2007. Every night at midnight the Dark Hour falls, and a tower called Tartarus rises out of the school. You climbed it alone, with AI-controlled teammates at your side.
P3F MMO is a fan project that will open that tower to online co-op. Friends will climb Tartarus together on an authoritative server, the days will pass on a real-time calendar, and the world, characters and battles stay the game's own.
It starts from the ground up. The game is being ported to PC from scratch, one function at a time, and every piece is checked against the original before it counts.
Each card says where it stands today: in development now, or planned for after the engine work.
Climb the tower with friends instead of AI party members. An authoritative server will run the game, so everyone sees the same floor, the same Shadows and the same fight.
A shared calendar that runs on real time, so the days move forward for everyone at once.

The PS2 game's code, decompiled function by function into readable C++ and checked against the original, with its own Direct3D 11 renderer.
Open the game like an engine. Change things while it runs and watch them happen.
Text and texture mods live in a mods folder. The port reads your changes from there and never writes to your disc image.
The port is rebuilt one function at a time. A function only counts once the game still plays exactly the same with it in place.
Playthroughs of the original game are recorded, including a full climb of Tartarus.
Every check replays those recordings on the port, with the newly rebuilt functions in place.
The result has to match the original byte for byte. If one byte differs, the function is not done.
On top of the rebuilt code sits a renderer written for PC, so the game draws through Direct3D 11 instead of the PS2's graphics hardware.
Four stages, in order. Multiplayer comes after the engine work, and there is no release date yet. Check back here to follow development.
Rebuild every function of the PS2 game in readable C++, each one verified against the original.
