Halo: The Master Chief Collection

Halo 3: ODST (2009) was added to the collection as DLC. People who played the collection between November 11th, 2014 and December 19th, 2014 received a code for a free copy of the remastered Halo 3: ODST as compensation for the Master Chief Collection's rocky launch.

When Spartan Locke refers to Master Chief as 117 in "Halo 2", Arbiter replies that he "was not told" his identity. This directly contradicts with the following cut scene showing the Arbiter's trial, where the Prophet of Truth calls him "Master Chief". This can also be rebutted in Halo 3, where other people in the presence of the Arbiter call Master Chief by this name including but not limited to Sergeant Johnson.

However The Arbiter wasn't referring to the fact he was unaware of the Chief's identity when talking to Spartan Locke, he was referring to the fact he was not aware Locke was looking for the Master Chief, he had only been told Locke was looking for a Spartan before Locke came to see him.
