In the new Spec Ops: Survival mode in Call of Duty: Modern Warfare 3, you won't just have to fend off wave after wave of human attackers, you'll also have to open fire on attack dogs and their more devious canine cohorts... attack dogs strapped with explosives. Call of Duty: Modern Warfare 3 is in development for Windows PCs, Xbox 360, and PlayStation 3 and is set for launch on November 8.
