Query: DeepMind Lab2D   We present DeepMind Lab2D, a scalable environment simulator for artificial
intelligence research that facilitates researcher-led experimentation with
environment design. DeepMind Lab2D was built with the specific needs of
multi-agent deep reinforcement learning researchers in mind, but it may also be
useful beyond that particular subfield.
