Idk wth happened but the last 7 minutes of the video got cut out. Spoiler. It's a buyable ending. Idk what happened and I don't have the footage anymore to fix it
53:12 that is the D13 sector from bo3 mp as a supply drop found in the secondary as a special weapon. And the spike launcher is from bo3 campaign from one mission I don't remember the name, but it's the mission with the longest dialog and a very slow walk at the start it also has a call back to Mendez from bo2 (I think it might be called demon within, but I'm not positive I just know it's one of the bo3 missions) as for the bo2 town part of stuff the TAC 19 pistol was not in zombies sadly, but It's still my personal favorite looking pistol and I don't know where the browning HP pistol came from. And yes I think the python and new model army share states (I don't know for sure I just assume because when you have python in the fridge and pull it on buried it's the new model army instead and when you put the new model army in the fridge it becomes a python on other maps.)
