Ok so i went and completed the marathon man achievement and i was suppose to get the security helmet it gave it to me for about 2 days. Now it says its locked and i would like for some one to tell me why and how to get it back.
I also have been told many things about getting other armor such as 1000gs give you the katana so if some one would tell me how to get other armor and what it takes that would be very helpful.
