Not undead nightmare, but the main game itself! Its a great story driven sandbox game with lots of optional side quests! Not to mention that the story is very emotional all throughout the game! Its sadly not available one steam from what I know so you'd have to play it on a console, but its totally worth it! Its definitely a game that the main character is developed so well that you feel as if you're fighting along side him the whole way through the game. I hope its considered!
