Halo 3 ODST will be the biggest new Halo game yet! It takes place just after Halo 2 when the factory blows up. All ODSTs were thought to be lost but some were alive! The begining starts just after the explosion where some ODSTs are trying to find each other. Although some of the Covenant forces have come back to scan the area foe any survivors. A new twist on the game is that there is no regenerating shields! You are now required now to find health packs to get health, so watch your back! The ODSTs also have a cool heat sensors visor so you can see all heat sensors. This will surely be the biggest new Halo game so far!
