Was wondering if it was actually worth getting 100% completed I play TLAD, so I don't know if it's worth it or not.

You get the ammo cap removed so you can buy unlimited ammo(doesn't carry over through saves so almost useless), and an anniahlator that doesn't give a wanted level that is no-where near a safehouse. They really cheaped out.

You get the achievement, only reason I can think of. Personal satisfaction?
