The team will share more details on the categories on February 25 at 10 AM PT. Stay tuned for more details on the official website

For those of you unfamiliar with Core, it is a new (free!) game creation platform that lets you build, publish, and play games. Core puts a game studio’s complex toolchain into one simple editor.

Core is a perfect platform for game jams as it allows you to quickly set up a 3D multiplayer scene. You can get started with making games right away with the help of thousands of free, high-quality music, sound, and art assets, with no coding required.

Core is powered by Unreal Engine, letting you create and customize games as you see fit, from custom game logic in Lua to primitives and models that you can kitbash together with visual effects to create an elegant scene.

For a deeper dive into how Core's kitbashing improves upon convoluted modern 3D art toolchains, check out our art director's blog post. And if you're interested in learning how far Core can take you as a professional developer, we've got you covered with extensive docstutorials, and even a generous monetization system.


  • Core gives you the power of the Unreal Engine with an easy-to-use interface.  
  • Core is simply the easiest way to create, host, and run a 3D multiplayer game.
  • No coding is required to create games in Core.  For those that want to get more technical, opt-in complexity allows for even greater control by scripting in Lua
  • With state-of-the-art tools like a built-in Terrain Editor, Performance Profiler, and skyboxes, you can create anything that you can imagine.


  • Tilesets allow you to get a good looking scene up and running far faster than in any other engine; check out a speed build video here
  • Check out some Impressive community creations from one of our previous jams in the style of American McGee’s Alice here.

If I'm a newcomer to Core, where's the best place to start?

Check out our complete introduction to the Core editor to quickly get up to speed and begin creating. For a more structured set of tutorials, follow along with our free courses at Core Academy.

What is the learning curve for Core?

Core is built using Unreal Engine 4 and shares many of the same hotkeys, shortcuts, and features as the Unreal and Unity Editors. Other features, including terrain sculpting and lighting work similarly to their Unreal 4 counterparts. 

Can I make unique-looking art in Core?

Yup! From high fantasy to dark wonderlands to modern military, the team has assets to match the mood - and thousands of primitives and materials to kitbash your own from scratch as well! The Core art director's blog post describes the ideology behind it all, for those who are curious. Check out the Alice video as well.

Where can I get feedback or help from other creators?

You can join the Core Creators Discord server, which has an active community of new and veteran Core users as well as a multitude of channels dedicated to art, design, programming, and critique. 

What do you mean by "art-focused" jam?

While having gameplay will help elevate your submission, the team will primarily be judging the submissions by their aesthetic merits for this contest. This includes accuracy to your location of choice, use of lighting, attention to detail, and the overall quality of your submission. If you are interested in including gameplay, note that the team provides plenty of tools to make it easy. You can see 'frameworks' (create --> new project) for full sets of game logic you can drag and drop into your map.
