Hey everyone and welcome to a different kind of video. Today, I am looking into Valve Source code leaks and an ambitious project by SADFI2259X (who is the reason why this video was made!), which is to backport some features from the leaked code into the 2013 engine (such as GameUI, Hammer etc.). This may not be the most well made video I could have done about this, but I believe I cover all of the points I wanted to make, plus I wanted to raise awareness of everything covered so people with more skill and/or experience can look into this if they want to. Please let me know what you think and I'll see you next time for whatever I decide to do! Thanks for watching.
