Q: What is “S&box”?
Q: Is there a release date? What about early access?
Applications for early access can be found here.
Q: Should I apply for early access?
A: If you’re a content creator (Programmer, modeler, mapper, etc.), have experience with either Garry’s Mod, Source/Source 2 or other game engines and are interested in helping develop the game/API and create content ahead of release then you’re good to apply. If you just want to playtest other people’s creations or create YouTube content about the game then the early access period probably isn’t for you. We can’t stop you from trying though.
Q: What platforms will be supported?
The game will not be available on Mac. Dedicated servers will be allowed to run on Linux, however, a game client for Linux will not be available.
Q: How much will the game cost?
A: We don’t know.

- Garry - Lead programmer

Q: What engine does the game use?
A version of Source 2 based on the Half-Life: Alyx branch of the engine. Early development was done on Unreal Engine 4 but this has since been discontinued.

At the moment both player and map size limits are the same as Source 1 (128 players and a max map size of 32768^3 units) but these limits are planned to be increased.

The implication here is that most limits can be worked around with some effort.

A: The official wiki is updated semi-regularly with info on how various systems work.
