I am trying to get my final achievement, Between Old Friends. I selected the final level, killer difficulty, and Cross as my skin. I played through the final level, beat the immortal, but I didn't get this reward.
What am I doing wrong?
I have only entered 4 cheats, the ones that unlock headshot mode, close combat mode, Wesly skin, and Cross skin. None of these cheats prevented me from getting "Dr. Lobotomy," "Butcher Would Be Proud," or "Heart Breaker" so I don't think they would cause a problem with Between Old Friends.
