Debug Menu

Early Czech copies of the PC version were accidentally shipped with the Debug mode on: Some modders later made a patch to un-dummy it in all versions, found here. Features include playing as Dante anytime, infinite jumps, invincibilty, disabling cutscenes, no-clip, and other options. A list can be found here.

To enable it on compatible versions, press and hold L1+L2 and then press R1 to toggle Debug Mode.
