Collect All Weapons and Weapon Parts
There are 15 weapons parts and 2 more inside of supply crates.
In order to get this achievement you will need to:
- Play through entire campaign making only positive choices
- Play through entire campaign making only negative choices
- Save all the hostages
- Find all the weapons parts
- Buy all the weapons
- Buy all weapon attachments (minus the styles)
Note: There are 2 guns that will only unlock if you have an original Army of Two game save; you do NOT need to have these guns for the achievement. The 2 guns are the AS-KRI and the S8-Z "Grand Pinger".
Note on Chapter 1 video
I forgot the first supply crate that holds a weapon part (G14 Thunderstrike). Until I can redo the video, it's location is in Chapter 1 after your first decision and after you kill 3 enemies.

Note on Chapter 4 video
On your positive moral playthrough, make sure to grab the G18C pistol. This can be found on the hospital level when the Doc opens a door to a weapons rooms, but this only happens if you have made positive moral choices up to this point.
