Halo 2 Cut Dialogue
Retail Cut Dialogue
The following dialgue can be found in the game files for Halo 2. They were either cut or not implemented, as they don't appear in the retail game.
Dialogue for the both the levels High Charity and Gravemind have the same prefix, "l07". Similarly, lines from both the levels Uprising and Great Journey have the same prefix, "l08". As the levels were originally intended to compose single levels, this could be an indication that these lines were added to the game before the decision was made to split most of the levels in half.
