SAN FRANCISCO -- While promoting its upcoming first-person shooter game Homefront at a staged rally, THQ released 10,000 helium-filled propaganda balloons. The only problem is that the balloons quickly came back down and many fell into the San Francisco Bay as it was raining and also because the balloons were weighed down by a Gamestop coupon for a Homefront multiplayer pack with a bonus in-game weapon. Local environmentalists were not amused, calling the stunt "polluting and littering." THQ claimed the balloons "were made from a 100% organic product and are 100% biodegradable." Check out this exclusive video of the rally and the balloons as they were released.
