  We present C-Procgen, an enhanced suite of environments on top of the Procgen
benchmark. C-Procgen provides access to over 200 unique game contexts across 16
games. It allows for detailed configuration of environments, ranging from game
mechanics to agent attributes. This makes the procedural generation process,
previously a black-box in Procgen, more transparent and adaptable for various
research needs.The upgrade enhances dynamic context management and
individualized assignments, while maintaining computational efficiency.
C-Procgen's controllable contexts make it applicable in diverse reinforcement
learning research areas, such as learning dynamics analysis, curriculum
learning, and transfer learning. We believe that C-Procgen will fill a gap in
the current literature and offer a valuable toolkit for future works.
