Browser is there for convenience, but it is not an ideal experience.  I recommend downloading the standalone game files.

[NOTE: Game is discontinued indefinitely. There will be no further updates.]

Multiplayer Survival game. Work with friends (or on your own, if you want) to figure out what's going on, and how to defeat the cataclysm. (Story is not in yet, however)

Launcher is windows only, and is recommended as it downloads updates automatically.

Please leave any feedback in the comments, this is pretty much my first non-jam game so i'd like to know what works and what doesn't. Link to the discord if you wanna chat!

Install instructions

When the launcher is installed, unpack it to a folder. Then, open "CataclysmLauncher.exe" and it should be downloaded, so long as you have an internet connection.


Cataclysm Launcher Release PLEASE 54 MB

Looking to make some improvements to the game's friendliness... so, if anyone could tell me why they are put off this game / why they don't like it, it would be appreciated.

No hard feelings or judgement, I just want to make a better experience.



Hey, wanna play this game with me?
