ok every once in a while a screen in the upper right hand side will pop up saying something like u have got -------- kills with----- or u have killed------- so many times was wondering if there was a way to track ur progression of this. Ive looked all though the pipboy and cant find anything

Its in the first tab of your pipboy if I recall. Don't recall exactly where it is, but I know its in there. Pay attention to the top right, it often says key) this screen.

It's the Challenges. In the PipBoy go to Data (3rd of the main three). then under Misc (to the right of Quests). There should be something in the top right corner that had a designation for Challenges (on PC I just hit 'R' and I go to them).

thanks mine only list 10 challenges. are there more that u acquire later in the game or is that it?
