The somewhat dreaded CERO Z rating is more common this generation, but CERO Z titles are still heavily restricted in Japan, a kin to ESRB AO (short for adult’s only) games in North America.

Square Enix hasn’t released a CERO Z game to date, but that’s going to change with Call of Duty: Black Ops. Even though it’s censored for Japan, it will be Square Enix’s first CERO Z title.
Gruesome scenes with limbs blown apart won’t be in the Japanese version because there is a ban on presenting that level of gore. The Japanese version of Call of Duty: Black Ops will use the same servers as North America. Other shooters like Singularity and Gears of War 2 have Japan-specific servers.
