Play Mewgenics together.

A free co-op mod for two to four players. Share one house and one pile of cats, or each bring cats from your own house and save. Either way, each of you is in charge of your own cats in battle.

free, no paywalls ✎

What does co-op look like?

There are two ways to play, and the host picks one when hosting. Shared house: the way we would have played over screen share, with one base, shared cats and shared resources. Separate houses: every player keeps their own house and save, brings their own cats and items into the run, and takes what they win home.

What's included?

Shared house: one house, inventory and cats for all players.
Separate houses: each player joins from their own house and save, and what a run unlocks lands in everyone's own save.
In a shared house, the host assigns cats to each player when starting an adventure, and can reassign them during it.
Each player controls their own cats in combat, and picks their level-ups.
Automatic installation and update through the launcher.
Automatic uploading of the logs to help fix issues with the mod.

How to install

Download the FFB Co-op.exe.
Place it in the Mewgenics root folder.
Run the FFB Co-op.exe. This will download the mod into a sub folder named FFB Co-op, update it, and then start it.
If successful, there should now be a host/join in the main menu.

Every player needs their own copy of Mewgenics. The original game files aren't touched: to remove the mod, delete FFB Co-op.exe and the FFB Co-op folder.

Who are we?

We're Fluffy-Fluffy and Bouncy: two friends who have played together since the Warcraft 3 Enfo days.

We keep ending up in management, simulation and turn-based strategy games, and far too many of them are single-player. For years we played those over screen share. Then it hit us: we write software for a living, so why not write the co-op ourselves?

We play what we make

We test the mod by actually playing it together. Most bugs are fixed as soon as we run into them, and every session's logs help us find the rest.

Free, and staying free

We make these mods because we want to play these games together, and we share them so you can too. No paywalls, now or later.

Mewgenics is just the start

The plan is to keep adding co-op to more games, whenever we find one we want to play together.

Want to help?

Play the mod, tell us about bugs on Discord, and tell your friends about us. That helps immensely.

If you'd like to chip in, Patreon buys us more time on the mod and pays for the servers. There will never be a paywall; support is a thank-you, not a ticket.
