I haven't worked on the project much because of study occupying my time and burnout.
However due to Team Fortress 2's 64-bit update releasing, an early update was needed.
This build does not have all features I wanted to release, but there is some nice changes.
I have also made the experimental builds for Garry's Mod and Left 4 Dead 2 public.
Stay tuned for an upcoming update with scripting support.

Thank you for your patience. Grab it here!
