Atlus’ political JRPG, Citizens of Earth for the Nintendo 3DS was removed from Nintendo’s eShop after an exploit was discovered that allows users to run modified or pirated software on a 3DS. A post on the Atlus USA Facebook page mentioned the removal of the game but did not mention the exploit.
The hackers behind the exploit that there was nothing special about the title that the exploit targets. They selected the title mainly because it was included in the Humble Friends of Nintendo Bundle and was therefore possible to be on many systems. The bundle sold more than 150,000 units.
The exploit is similar to one found in the indie puzzle game VVVVV, a title that was removed from the Nintendo eShop on May 3rd. Both games are still off the shop as of this writing.
