Not the best add on for borderlands but it is still fun.

My biggest complaint is how short this add-on is considering the Secret Armory of General knoxx added around 9 hours of gameplay. While despite all of this repetitiveness this add-on is really fun if you enjoy Borderlands. They seemed to continue with how funny the game is and the missions are very fun. I don't want to give much away but the last mission is great and brings back a lot of memories about the game. One thing that sucked was that the DLC came out without the update for level increase which is kind of B.S. considering you had to wait to gain any extra levels. While this DLC doesn't add too much its a great way to get back into Borderlands. Now I can only wait for the second Borderlands to come out and play this one until it does :) Don't get me wrong anyone who enjoys Borderlands should enjoy this DLC a lot should look into getting it because it is very fun in many cases if you play with a friend.
