Games Like Horizon Sandbox

Horizon Sandbox is a multiplayer physics sandbox where your creativity takes center stage. Bolt a thruster to a wooden pallet and call it a plane, construct massive mechanical structures, or just cause chaos with friends. There are no missions, levels, or objectives - every server is an open sandbox where you and up to 100 other players build, wreck, and collaborate however you want. Build anything, the only limit is your imagination!

Features:

Sessions can run anywhere from a few minutes to several hours, depending on what you're building and who you're building it with.
