As if creating games within a 48-hour time window was not hard enough, we're inviting you to take part in a challenge: create an online multiplayer game using coherence during Global Game Jam!
To ease your mind, we know for a fact it can be done.
The deal is simple. Just take part in Global Game Jam during its normal schedule, online or at your favourite local site, and make a multiplayer game using coherence.
Then submit it here too, and we'll make sure to reward the best ones.
In addition to the personal gratification of giving yourself this extra challenge, we’ve decided to reward the most innovative multiplayer game ideas with $10,000 worth of prizes!
If that sounds like something for you, sign-up to the jam on this very page!
To sign-up for the game jam:
We align with the schedule of Global Game Jam, but we allow for a little extra time to submit your game to our challenge, so you can iron out details or fix some last-minute bugs.
You can read the rules of the contest on this link.
What is coherence?
coherence is a network engine, platform and a series of tools to help anyone create a multiplayer game. Our mission is to give any game developer, regardless of how technical they are, the power to make a connected game.
coherence offers an SDK for Unity that allows to very easily sync the state of GameObjects across multiple clients, to make them persistent across game sessions, and to create game logic that is simulated on the server. Or to do all these things together.
What is the Global Game Jam?
Please refer to the Global Game Jam FAQ.
What software or assets can I use?
We only ask you to use coherence (which implies using Unity). For the rest, you can use any third-party plugin, Asset Store assets you own, or custom code you wrote before.
Can I bring a game already in development, and add multiplayer to it?
No, the game needs to be created as part of Global Game Jam.
Do I own the games I make?
Do I have to share the source as part of my submission?
No, we only require you to submit the game build here on itch.io. However, the GGJ guidelines ask you to submit the source of your project on globalgamejam.org as you submit your game during the Global Game Jam weekend.
