This is our attempt to create a worthy Garry's Mod sequel.
We've been playing with it for a long time. It started off on the Unreal Engine, but now it's being developed on Source 2.
It's not going to be Garry's Mod 2. My hope is that it will eclipse what is possible in Garry's Mod rather than simply be a modern version of it.
The current status is "heavy development". The aim is to give some people access in the first half of 2021, and give everyone else access in the second half of 2021.
