Middle-earth: Shadow of Mordor Season Pass
Worth it, especially for the price!
Besides the outfits and new enemies this included The Hunt and the backstory of the wraith. It actually gave me a reason to pick up the game again and play the add-ons. While the other things were small they still added to the overall experience of the game. So for $25 this actually was a good buy and I'm happy I got it. Only reason I didn't give it a 10 out of 10 is because while it was inexpensive and the add-ons were fun, some didn't really make a difference in the game, but were still cool.
