You can't be serious.
The game was released in a broken state, and it was well known. You do not playtest a game and just so happen to miss significant bugs, many of which were so bad that the game was unplayable and crashing. I'm sorry but this does not happen and what you are doing might as well be corporate ballwashing.
This happened because Microsoft took over publishing and thus got rid of much needed regulatory stops for a game before release. Microsoft knew this, 343 knew this, Frankie knew this. They kept their mouth shut before it released, spitting in the faces of their former fans.
There is zero defense for how this game was made and released, none.
