Start Game > Continue

You will be in a restroom with the megaman blaster on hand. As soon as you start moving you will unlock the "Marathon Runner" Trophy.

Head out of the restrooms and kill a soldier to unlock the "Legendary Soldier" Trophy.

Pick up the gun the soldier dropped and head to where you killed the butcher. (where you got the punisher and collector trophy). Clear out the zombies with the supplied queens and now look at those meatsacks hanging. Make sure your left shoulder is facing the door and you're looking at the thing hanging lol. Aim and unload on it and when the weapon breaks you will unlock the "Perfect Gunner" Trophy
