About Onset

Onset is a multiplayer scripting sandbox where you create and host experiences using Lua, or play game modes made by other players. The default map is completely empty; you use Lua functions to build its content and write game-mode scripts that run on the server or game client.

Create with Lua

Onset provides over 400 Lua functions for customizing the world. You can use them to spawn cars, helicopters, NPCs, objects and more, and load custom maps. You can also import characters, animations, props, sounds, particles and other content.

Game modes and servers

You can play alone on a localhost server or join multiplayer. Dedicated servers support up to 300 players, and you can host your own server with your scripts. The game also includes different modes created by other players.

Vehicles and weapons

Onset has various types of vehicles, each with a damage model. You can mod weapons and configure attributes such as damage.

Communication and interface

The game includes an in-game VoIP system and supports UI customization with HTML, CSS and JavaScript.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
