So Just start XCom 2, and I'm new not only to XCOM 2 but also the XCOM universe.
Anyways can't figure out something which is supposed to be very basic and which is why it's so frustrating: How do you upgrade weapons?
I have a scope I looted from enemies and that says '+5% accuracy'. But I just cannot figure out how to attach it to a weapon? Any help?
Thanks in advance.
