Halo 3: ODST Hint: Hidden Skull Locations

Hidden skulls have been with the series since Halo 2, so naturally ODST brings with it a unique set of hidden skulls to find. There are three total, each hidden inside one of the new multiplayer maps. Fortunately, you don't need to search for the skulls while in the midst of a multiplayer battle—in fact, you'll need to find them in Forge mode (Forge is available on the multiplayer disc). Load up the level and use the flying camera mode to navigate to the skull locations, which we've outlined in the video below. When you've found the skull, position yourself above it and then toggle out of the flying camera mode and hold whichever button you've got mapped to picking up weapons (default is RB). Your character should fall past the skull and pick it up on the way down—if you miss it, just try again.

Halo 3: ODST Hint: Mongoose Mayhem in Mombasa

If you are getting tired of trekking to those Data Terminals in the New Mombasa segments, you should know that there are secret Mongooses available for you at the Superintendent Supply Caches. Pick one up in the northwest corner of the map -- where you start out -- once you've unlocked the cache there.
