SonicGDK (short for 3D Sonic Games Development Kit) is a codebase, a collection of source codes, which allows anyone to create 3D platformer video games based on the Sonic the Hedgehog franchise. It can be freely modified and is integrated with the UDK, providing you with a modern game engine in which to develop your game.
This is the test map of SonicGDK labeled as Packaged Release 6, try it and have fun!
how do you change your map?
Does this require udk to run, because it isnt working
It should work, this is standalone, but very old...
I really like sonic gdk, but where are the chaos emeralds?
When I tried it, there were no chaos emeralds.Somehow, someone had the version where the chaos emeralds were hidden.If they aren't hidden, then you have to jump into a big ring that appears when you start(you need to do the special stage).
