This installment of the franchise offered players a perspective of how the world could have changed for the worst. In an alternate reality where the Nazis have won World War II, players must fight along with the resistance, in order to claim Earth back from the hands of the Third Reich.
Throughout the journey, players encounter many types of enemies, including the Mech Dog. While it is not very strong, its agility makes it perfect to ambush players that will need to be faster than the machine.
This enemy offers balance in the experience, as most of the enemies are human and move slowly. The mech dog changes that and developers often used it to catch players off-guard, using the old trick of creating patterns and then breaking them. Once players had become accustomed to the normal enemies, the game caught them by surprise, by throwing the mech dog in the combat.
