If you’re having a long weekend on your hands to play Halo 3: ODST and you’re looking for the Audio Log locations, we just got our hands on an HD video guide and a bunch of screenshots to help you on your mission.

To set the things straight, there are 30 audio logs available on Mombasa Streets. Each and every transmission (a different story every time, about a girl named Sadie) can only be gathered by the Rookie at night and in the Normal, or above Normal difficulty settings. Collecting them either alone or in cooperative play — the order doesn’t matter, unlocks 4 achievements worth 125gs.

Slated for a September 22 release date in Europe — which is today, the new Halo 3: ODST will try to get you further into the sci-fi universe by packing an exclusive beta key for Halo Reach. As good as it may sound, it looks like Microsoft hopes that featuring the Halo Reach multiplayer Beta (only live in 2010) on the new Halo 3: ODST disc will act like a sales enhancement for those looking to experience the amazing Halo world.

“We saw the success of this mechanic with the Halo 3 multiplayer beta that came on the Crackdown game disc and the continued sales momentum and excitement generated around that title throughout its lifecycle, and we fully expect Halo 3: ODST to exceed that achievement,” said Xbox head of gaming and entertainment devices UK, Stephen McGill.
