Welcome to the IGDA x Core Summer Game Jam! This completely virtual game jam uses Core to empower you to make amazing games over the span of just three weeks!  Download Core here.

Theme: Summer Festivals

This year’s theme is ‘Summer Festivals’. Whether you’re enjoying some rides and live music, drinking in the beauty of the sun-kissed treetops that tower over your favorite amusement park, or laughing with your friends as you nail the bulls-eye and send them into the dunk tank, there’s endless fun to be had! An abandoned carnival full of shadows, a summer fair brimming with mini-games, a concert filled with music - all are welcome!

Core is the new free game creation platform that lets you build, publish, and play games. Your game must be created in Core to participate in the jam.

Core makes prototyping and iteration fast, so it’s a great platform for Game Jams, especially if you want to quickly set up a 3D multiplayer experience. You can get started making games right away using thousands of free, high quality music, sound, and art assets, with no coding required. 

Core is backed by the power of the Unreal engine, and it lets you create and customize your game as you see fit, from custom game logic in Lua to unique models you can combine from kitbashed primitives to a fully featured terrain editor.

Check out the following video of how to create and publish a multiplayer-ready game in 10 minutes!
