THQ is catching some flack for a Game Developers Conference promotional stunt for Homefront that involved the release of hundreds of red helium balloons over San Francisco, reports CNET, saying residents are particularly upset over balloons that ended up in the bay. The balloons carry the GameStop logo, and so the game store has borne the brunt of the blowback on this, but they have stated they were not aware such a promotion was happening, which was later confirmed by THQ. GameStop also says they were told these are "soy-based, biodegradable balloons," and THQ has also said the balloons are biodegradable, though they did not mention the soy part (latex is also biodegradable). "The balloons released at the Homefront rally event today were made from a 100 percent organic product and are 100 percent biodegradable," THQ said in a statement. "The balloons have no history of causing any environmental pollution on land or in water. Although we're confident that there will be no harm to the environment, we've retained a cleanup crew to remove any potential lingering debris. This was a THQ sponsored promotion and GameStop had no involvement, whatsoever."
