MDK2 Armageddon Codes (PS2)

MDK2 is a video game and sequel to the third-person shooter, MDK. The original MDK was developed by Shiny Entertainment and released in 1997 by Interplay. For the sequel, established RPG developer BioWare Corp. of Edmonton, Alberta, Canada took the reins, delivering a highly rated gaming experience that followed on closely from the first game.

MDK2 was originally released for the Dreamcast and PC in 2000. It was later revised and released for the PlayStation 2 as MDK2: Armageddon.
