The Arcade Learning Environment ("ALE") is a widely used library in the reinforcement learning community that allows easy program-matic interfacing with Atari 2600 games, via the Stella emulator. We introduce a publicly available extension to the ALE that extends its support to multiplayer games and game modes. This interface is additionally integrated with PettingZoo to allow for a simple Gym-like interface in Python to interact with these games.
