Hornets' Nest is the third chapter of the fourth act of Gears of War 2. Objective: Move to the Locust Palace During this mission, the player must fight their way through multiple intense firefights while making their way towards the Locust Palace. It is the first time in the game (or indeed the series) that the Palace and the Butcher are seen. It is also revealed what the Locust see as a food source; Marcus and Dom find the severed remains of an eaten Rock Worm, prompting Dom to say, "Well, guess we know what the grubs like to eat".
