Welcome to the first Planetary Processing Game Jam!

The name of the jam is simple - make the best multiplayer game in 10 days.



๐ŸŒŸ What's this jam about? ๐ŸŒŸ


This event is to get developers to design games which thrive from having multiple people online. 

We have been making an online engine for multiplayer games. Now we want to get people jamming on it, to make the coolest multiplayer they can. We judge your games, you judge our engine. 

There will be voting, there will be judging, there will be prizes!





โœจ What's going to happen? โœจ


Although this is a multiplayer jam, a theme reveal will kick off the start of the jam. Treat this theme more as a creative prompt rather than judging criteria. What we really want to see is multiplayer games which could not exist in singleplayer alone.


It all starts on 31st Jan, and runs for the first 10 days of February. 

Then a week of community voting and judging by the Planetary Processing team. 

At the end there will be a stream announcing results, and of course prizes.


Multiplayer game jams work best with lots of players, so please share your games and the jam as much as possible in the meantime!

๐Ÿ“ Rules: ๐Ÿ“

โšช Any of the following game engines may be used to make your game: Unity, Defold, Godot, Unreal Engine 5, or  Lร–VE.

โšช The game should use the Planetary Processing Engine for its online multiplayer.

โšช The games must not be discriminatory or include NSFW content of any kind.

โšช Pre-built art, audio, libraries, and game assets may be used, as long as you have the commercial rights to use them. Prebuilt code may not be used.

โšช Assets or templates supplied by Planetary Processing can be used in your game.

โšช Instructions and narrative dialogue should have an English translation.

โšช You can make teams of up to 5 people, if you want, but you may only be part of one team. Find teammates on our Discord.

โšช Games may also be submitted to other jams, if their rules allow it.

โšช Any game submitted may be used to gather promotional material/media for Planetary Processing. The game itself is undeniably yours and we claim no rights or ownership to it. We mostly just want to share and stream it.

โšช Games must be built to be played on PC.

โšช Games will be judged by the Planetary Processing team and prizes awarded. There will also be a community vote, using the itch.io rating system.

โšช  Any submissions deemed to be breaking the rules or disrupting the ethos of the jam will be disqualified.
