Onset - Open World Scripting Sandbox


Onset is a scripting sandbox game made from the ground up for multiplayer. Create and host your very own experience in Onset using Lua scripting functions. Or just enjoy the different game modes created by other players.

Key features:

  • Over 400 Lua functions to customize the world.
  • Spawn cars, helicopters, NPCs, objects and more with Lua functions.
  • 300 player dedicated multiplayer servers. You can host your own server with your scripts.
  • Various types of vehicles with damage model.
  • Weapon modding including configuration like damage.

What can I do in Onset?
By default the map in Onset is completely empty. The Onset developer wiki holds a list of all Lua functions including descriptions on how to use them. With those functions you can write your own game mode scripts that either run on the server or game client. This way you have endless possibilities to realize your idea in Onset.

Import of 3D Models
Since Onset is based on Unreal you can import static/skeletal meshes, materials, textures and sounds. We have a modding tool that packages the content in the Unreal Editor as a .pak file. Check out our wiki page for more information: Modding - Onset Developer Wiki
