Reverse Collapse: Code Name Snake Eater Chapter 4 Final Route:My Lone Infiltrator Can't Be This Cute 

I decided to try something different for this video, it would be perfect if I can get a hold of Mendo shouting for Jefuty's voice line to finish it off perfectly but oh well..
Collectible is easy to get, just have at least 1x comic left in inventory before you end the mission, the mission is still played in challenge+
