Slow news day, but this news should excite the gamers in our audience. The third installment of the BioShock series, BioShock Infinite, was announced today. Instead of the subterranean city of Rapture featured in the first two games, Infinite takes place in a city above the sky called Columbia. The game is being developed by the original BioShock creators, so it should be great. Check out the awesome HD trailer below.
