Gemini is an online game service created specifically for use with UDK. It was born out of frustration with Steamworks, lack of documentation, and a primitive existing TCP-Link system. Gemini streamlines the development process by allowing you to set up an online base in minutes. No more messing with complicated SQL and domains!
