It looks like Square Enix is editing the contents of its upcoming game in order for it to be released in Japan. The game, (called Sleeping Dogs Hong Kong Secret Police in Japan and Sleeping Dogs in other parts of the world) developed by United Front, will be edited to fit the market in some bizarre ways.
Besides getting a rating of CERO Z (adults only), the game will be edited with a system that punishes players for killing civilians. We have no idea what that punishment will be, but we imagine it will be much more than a "time out."
The game is scheduled for release on August 14 on multiple platforms. It will be released in Japan shortly thereafter.
