Well at least it tried
As a played though this add-on it felt like it was leading up to something big. With all the diffrent machines you come across and the abominations you run into later on and the omonious alien head but it never got there. This was the final DLC and it should have gone all. Instead your left with coridoor crawling repetative actions with an ocsional interestiing machines that make you think "what was this for". Yet nothing is explained. The gunplay was fun and you pick up a few unique wepons but nothing really stands out. I would say its a fun couple of hours its worth your time but not your money.
