S&Box, being slated at Garry's Mod 2 (unofficial) was announced earlier this month. Not much is known about it just yet. It's in it's early stages of development and a public release has yet to be announced either. More info can be found on the website and there is also a subreddit but it doesn't have much activity yet. I'll update this thread if new info comes out, but so far here is some of the stuff we can look forward to if/when it releases; Developed by Garry Newman/Facepunch Built in Unreal Engine 4 not Source 2 Support modding through C# Console will be a secondary app HTML will be used for UI Port maps from Source or GoldSource without having to convert From Layla:
If there were to be a gmod 2, it would take a while to develop. Also, if there will be a gmod 2, I really hope that it won’t be half assed. It would be nice to have a new and improved gmod, with less bugs. Oh and btw, it won't be called garry's mod 2.
