I give the Gears of War 3 Horde mode a 9. I give it this score because its a great game mode-but its too easy. I can play through it on any map on Insane and only die a few times. I haven't purchased any DLCs for this game, and I don't use Mutators very often. Once you learn where the enemys spawn, its very simple to plant a Boomsheild in their way, and then hide yourself in a space such as the upstairs part of Overpass, and shoot anything that moves. Your ammunition replenishes to a good amount whenever you finish a wave, and its not hard at all to protect yourself. Just kill the hell out of everything and spend the money on barricades and your good to go. Turrets help as well.
