Capcom plans to have two versions of its Resident Evil 2 remake in Japan. One is going to be a standard version called Biohazard RE:2 and the other will be the more mature Biohazard RE:2 Z Version. The former will carry a CERO D rating, which restricts it for 17 years old players or older; the latter comes with a CERO Z rating, which is meant for 18 years old or older players. The “adult version” will contain more gore than the standard one. Biohazard RE:2 will censor some of the gore and violence in the Z Version. Now, we can’t say how much it’ll censor as the game is still in development.
