I've been working on a brand new Sandbox gamemode that aims to replicate the original features of the Sandbox gamemode from the Entity system with the look and feel of Garry's Mod (along with some features that are in Garry's Mod but weren't in the Entity Sandbox gamemode, like Undo).

Soon! I'm currently implementing a basic Main Menu so you can actually create your own lobbies and join servers from a list so once that is done you can expect the first version to drop. This will have just about everything Entity Sandbox had minus any sort of Entities and missing many of the Tools.

As time goes on I will slowly push updates with more tools, features, ect.
