If I wanted to look for items with no real objective in mind i'd play an mmo. With this, i want to work for it via achievements, at least then I know what i have to do to get the weapons instead of just sitting with my thumb up my ass and hoping for something I don't have yet (which I didn't get, my only unlock -in 8 hours of playing- was the blut. whoop-de-fucking-do. I even deleted it from my 'inventory'.)
