Reunification (Command & Conquer 3: Kane's Wrath)
In the first act of the campaign (set immediately after the conclusion of Tiberian Sun), Kane enters a bunker deep in the Earth's crust apparently healed of all injury save for his face mask. He instructs the player to begin the Rio Insurrection by taking out the GDI presence in the area. After the player succeeds, Kane informs the player of his plan to reunite the Nod splinter factions. Since he cannot risk revealing himself to the world yet, he chooses Brother Marcion, the leader of the "new" Black Hand to convey Kane's will to the Brotherhood in his stead. The player is then commanded to drive Marcion out and capture him. Brought before Kane, Marcion comes back into the fold of the Brotherhood as Kane reveals himself to him, and removes his face mask, showing a completely scar-free face. Kane then orders the player to destroy a Liquid Tiberium facility in the Australian Outback as a 'grand gesture' to the remaining splinter factions to rejoin him.
