I remember reading a fic about Cap finding a training room Tony created that has fake Daleks that you can fight. At some point he manages to activate the Doctor in the program and he manages to win. Does anyone know this story? I know this isn't much to go on but really that is all I can think of at the moment except that Steve has no idea what a Dalek is. Thanks in advance for any help.
Edit: found by rakelnott! FROM the series Don't Look too Closely (all the angles are oblique). It's in We've Done this Before (as Mars Sauntered Through His Door).
Sorry about the lack of links my phone is being uncooperative. see the comment below.
