Gears of War 2 Cheats :
Easter Egg - Who wants Toast?
On Act IV, Chapter 5, in the middle of the level, before heading down the spiral staircase to head to the Queen's room, take an immediate left. If you go all the way to the edge of the half-oval space, there will be a little box with a Locust symbol on it. Shoot it, and there will be a little purple toaster that pops out. Press X, And some burning toast will pop out of it.
Also, Marcus will give a little dialogue saying, "Who wants toast?"
