It's like Garry's Mod - we provide you with the tools and you can do whatever you want with no predefined goals or objectives.
  • Spawn props and entities from the cloud to build whatever you want
  • Use your Toolgun to weld pieces together, add wheels, thrusters, balloons, hydraulics and more!
  • Explore community-made contraptions or make your own and share them 
  • Mounts let you spawn in content from supported games

Q - Opens the Spawn Menu, for spawning entities, picking tools, and controlling everything.
C - Opens the Context Menu, if you click objects in the world, you can edit them.
X - Toggle First / Third Person
TAB - Scoreboard
ENTER - Chat
V - Voice Chat
SPACE - Jump / Noclip if pressed twice

Sandbox is now open source!
