The huge Halo 3 ODST booth on the Gamescom showfloor was all about multiplayer. To see the first levels of the solo campaign, we had to sneak into the Microsoft hideout, safe from prying eyes. There, two lieutenants from Bungie gave us a fifteen minutes long presentation of this spin-off to the Master Chief's adventures, a spin-off which story runs parallel to Halo 2's. With its open world structure and daring flashback narrative, Halo 3 ODST doesn't fail to surprise, right from the long and intense introductory sequence that we offer you to discover just after the jump.
Update: Second part is online.
