The Chadley Combat Simulator, abbreviated to CCS, is a battle arena in Final Fantasy VII Rebirth. It is a simulated arena deployed by Chadley in which participants fight battles in a virtual reality setting.

The Chadley Combat Simulator is available from Chapter 2, "A New Journey Begins". Wherever Chadley is encountered, the player can ask to partake in in the battle arena. The combat simulator includes battles for each party member, battles against the region's summoned entity to obtain its materia, battles against enemies fought as Fiend Intel and Classified Intel, and battles to learn abilities for the Enemy Skill Materia.

After completing the main scenario, more challenging battles are unlocked after completing the game, and the most difficult fights in the game are found in the simulator.

Items cannot be used in any challenge. Between each round, 50% of HP and MP is restored.
