Forever - Endless Runner Engine

A user-friendly, flexible solution for the generation of linear, procedural levels. Forever is ideal for endless runner games, procedural racing games and more. Forever is now free for everyone to use commercially.

Used in the creation of Lifeslide

Key Features:
- Procedural path generation
- Automatic mesh and object extrusion along the generated path
- Multithreading support for the generation process
- Object Pooling
- Works great on mobile
- Works for both 3D and 2D projects
- Easy and straightforward setup
- Offers built-in logic for traversing level paths
- Minimal programming skills required to write player behaviors
- Flexible and easily extendable functionality
- Open Source
- Level streaming feature for bigger projects

The way Forever works is by extruding and snapping together level segments. The level segments are special kinds of prefabs that are created inside the Unity editor. Use the tools you know to create the level design for each segment and let our system do the rest.

Since we are using it to develop our own titles, Forever is constantly being worked on.
