We develop tools for our own use. The ones that become good enough, offer enough functionality and utility we publish on the unity asset store.
Custom Quest is our quest system, in which quests, missions and objective can be crafted to your hearts desire. It is available on the unity asset store now
Custom Controller Input is a tool for easily creating and changing interactions with controllers for your game, making it fast and easy to test new control schemes. It will be available on the unity asset store in 2017.
