Though the UNSC manages to repel most of the fleet, a large ship hovers over the city, depositing an invasion force. The ship eventually retreats via a slipspace jump, creating a massive shockwave. The tale can also provide useful information for the player during the game, such as helping to locate hidden caches of weapons. He finds Romeo instead, and the two resolve to find the others and get out of the city. Mickey commandeers a tank and fights his way along a Mombasa boulevard.
Concept art of Sgt. ODST's campaign, Firefight is a cooperative game mode that lets you and up to three of your friends put your skills to the ultimate test. It allows you to jump straight into the heart of Halo and experience traditional Halo sandbox encounters with a new, high octane twist. Throw game play modifying skulls into the mix and you'll find that the combat can become even more interesting and intense. There are five Waves in a Round and three Rounds in a Set.
