OpenNERO consists of the core program and a collection of one or more mods. A mod is a logically separate unit of OpenNERO that can be a custom game, an AI experiment, or both. Each mod is defined as a directory next to the application. When you start OpenNERO, it shows a menu with existing mods and an option to exit. Currently, the following mods are included:

Maze - a simple maze world on an island, with search, learning and first-person agents.
Blocks World - a classic AI problem for planning and natural language understanding.
Roomba - a messy computer lab which gets cleaner with the help of some cleaning robots.
NERO - an implementation of Neuro Evolving Robotic Operatives (NERO), where you can evolve your own team of neural network-driven robots along a variety of fitness criteria.

The controls can be easily redefined, but in general, the following keys should work:
