Brian has posted his review of Halo 4. Here is an excerpt:
Bungie out, 343 in. Master Chief is back from his space odyssey and eventually frozen for preserve, leading to a new Halo reprise. Microsoft kept John on ice while the new team at the helm took over the story line. The shoes to fill were not just big, but they were probably the largest shoe size in the industry. Arguably the largest gaming success in the history of all gaming, 343 would need to pull out all stops to satisfy the hungry Halo fan base. Starting and continuing where Bungie left off is just the beginning for Master Chief and the Halo committed fans.
