I just wanted to this to be a quick update so everyone knows what's going on.
We've only had the engine for a month and have been spending that time getting set up and exploring. I'm hoping to be able to post some progress and invite people to try it over the next few months.
I'm also looking for people to join Facepunch to work on Sandbox. Anyone with decent experience of Source1/Source2 - whether that's programming gamemodes/addons for Garry's Mod or creating maps.. at some point we're going to need people to help us make content.
There's a job link in the header of this site if you think you fit the bill.
