A downloadable game for Windows, macOS, and Linux

Epicinium is a multiplayer strategy game where the players' impact on the environment matters. Combat destroys grass and crops, and trees are trampled as tanks drive towards your opponent to level their cities. Industry accelerates global warming to ludicrous levels, causing more destruction the longer the game goes on. At the end of the game, the winner is scored for how many grass and forest tiles still remain on the map.

Epicinium is being developed by Daan Mulder and Sander in 't Veld and is available for Windows, Mac and Linux. The game is currently in open beta.

Weekly playtests

Every Saturday from 19:00 UTC and lasting a couple hours, we hold an online playtest session. Download the client and join in for some fun and games! We also livestream these events on Sander's Twitch channel.

How to play

Epicinium is a multiplayer strategy game with simultaneous turns. Each turn consists of a planning phase, where all players decide which orders they want to give their units that turn, followed by an action phase, where players watch as the the orders play out. 

Units will automatically attack enemy units they encounter; they will also fire back when attacked and attack any unit that moves away from them. Some units have abilities that allow them to bombard tiles, randomly dealing damage to whomever and whatever is present at that time. Anticipating your opponent's orders is key.

Between rounds, the season changes which might bring about new weather effects such as snow, drought or firestorm. At night, buildings can gain power and generate income. Cities only gain power if surrounded by enough grass, forest, water and crops, whereas barracks and industry grow larger when additional cities are placed nearby.

To defeat your opponent, capture or destroy all of their City tiles.

Install instructions

Extract the archive somewhere on your system where you have full writing permissions (your Documents folder, for example). To start playing, double-click the "epicinium" executable in the folder where you extracted the archive.

On Mac, you may need to right-click the executable and then click "Open", as otherwise you get an "unidentified developer" warning that you are unable to ignore.

If that does not work for you, please consider installing Epicinium via the itch desktop app. We are also happy to assist you at support@epicinium.nl or in our Discord server.

I've won my first game vs MediumTurtleIA, it was really nice to play. No tech issue it seems, playing on Linux Mint. Thanks for the support, and i wish you succeed, it's a fun game already.

Thank you very much Tchey! I'm glad you had fun and that it worked on your system. :-) SLiV, my co-dev, is also an avid user of Linux Mint. If you'd like to chat with us or find some opponents to play Epicinium with, you're very welcome to join our Discord.


Se ve interesante. Descargando en Arch Linux.

¡Hola CeesarL2002!

I'm afraid that's all the Spanish I know, so I hope it's okay if I continue in English. Thank you very much for downloading Epicinium. I'm curious what you'll think of the game, and whether it works at all under Arch Linux. We compiled under Debian 7, so there's a big chance that the binaries won't run in your distribution. Please let us know whether it works.


The game starts well. I can not use the mouse, so I understand that I only need the "Enter". But I do not know how to start the game .-.
I do not speak English, so this is from the Google Translate xd

Hi! The game is controlled with the mouse. There are some keyboard shortcuts but not enough to play the game. Why does the mouse not work? Is the cursor position wrong? Or does it not move at all?

On a hunch, could you try running the game from the terminal using

SDL_VIDEO_X11_DGAMOUSE=0 ./epicinium

from the directory that the binary named "epicinium" is in? If that fixes it, we can add that to the next version.
