Ok, in ODST, we shall delve a bit into the past of some of the squad. This will probably be Buck and Dare only though. It will have 10 or more missions. About 4 of those will be flashback. The campaign will feature the ODST's fighting the Covenent before the destruction or news from the ark. Dutch will die and mickey will go AWOL for revenge. The squad will split into different groups. Rookie with Dare and Romeo with Buck. On the way into the Covenent planet/ship, they'll find Virgil captured by the Covenent to kill all the humans, or hijacked/sent to help and hacks into the mainframe. They find that for their new weapon/experiment, they need a dead human body for DNA and battle strategy to have a clue on what the ODST's will do. They hack into the cameras and find Mickey about to be harvested. Mickey helps by setting up explosives throughout the ship. They are about to escape when Mickey says he made a promise to Dutch. They go find his body and carry to the escape area. There, it turns out that the unfinished creature is there, waiting for them. They almost kill it but then it's grabs Dutch. It starts to assimilate his body. You then take control of Mickey. You kill the creature. You retrieve Dutch's body. After the escape and credits. You see Mickey's promise; have Dutch flash-cloned so he can live one last day with his friends and family. I know this is a bunch, but here is basically the plot to ODST 2 with the flashbacks and ODST 3 with dead dutch [Edited on 06.27.2011 5:33 AM PDT]
