This video guide will give you the exact locations, in order, for every collectible in this mission. Unfortunately, there's no commentary to aid you along the way. Just turn your brightness up, take your time and you'll be ok. If you find a collectible and die before a checkpoint, it's best to go back and pick it up again just to be safe.
Please keep in mind that any mission-specific melee/firearms picked up won't count unless you finish the mission.
