Does master chief appear in halo odst?

He was in Halo odst, however, indirectly. If you have played Halo 2, you can see the ship (Amber Clad) in the first cutscene of Halo ODST, where the odsts were dropping, and the slip-space jump took place. Look at the right side of the covenant ship and you can see a really small UNSC ship; masterchief is in it. However, masterchief didn't participate in this game.
