This is it folks. I am pulling the trigger (finally)!
As of today, GoldenEye: Source is now an open source project. I have uploaded our entire code base onto GitHub. This code base aligns with SDK 2013 from Valve and v4.2.4 that was last released (with minor improvements).
https://github.com/goldeneye-source/ges-code/tree/ges
All our main code base is under the following folders:
/game/client/ges
/game/server/ges
/game/shared/ges
It is still in a pretty rough state since porting over to SDK 2013. There is a lot of work to be done still, but there it is. I will accept pull requests for capability and bug fixes, but not for added features or major revisions of code. Please use GitHub's issue tracker for any known issues you would like to see resolved.
Look forward to an updated contribution and usage license coming soon as well as a list of Valve files we have modified to suit our needs.
