[quote] 1. Bungie said so. 2. Different dates. 3. Name of the ship is Forward Unto Dawn, not Marathon. 4. Different aliens. 5. Bungie said so. [/quote] 1. Alex Seropian said MC and SO were the same character 2. Marathon takes place 200 years after Halo 3. MC is cryo-frozen, possibly allowing him to live for so long, OR if you go with the alternate universes thing that a bungie employee said at a later date, the portal to the ark that sliced Foward Unto Dawn in half, might have sent MC's half into an alternate universe, IE the marathon universe. Theres a thread on that. 3. Yeah, the name of the ship MC is in is forward unto dawn. Marathon is the big planet-sized colony ship or w/e that is widely believed to be the planet that Foward unto dawn is floating towards in the legendary ending of Halo 3. There's a marathon logo on the planet. 4. There ARE different aliens in the halo universe. At the end of halo 3, the flood that escaped containment are destroyed, the rest are still contained. The covenant is dead, the elites go back to sanghelios, humans would prosper, and in marathon, the human civilization is HUGE. 200 years with no competition for colonization tends to do that to a race. 5. Alex Seropian said they're in the same universe (also read alternate universe theory)
