Borderlands is one of the best co-op games out there (only overcome by the recent Borderlands 2)

Co-op is incredibly fun

Although it provides little for a story; epic bosses, enemy variety, thousands of guns, open environments, plenty of character customization options, and seamless co-op go a long way to smoothing away this shortcoming.

An excellent co-op experience

Co-op play is great, but the experience loses something on Xbox Live

The single player is really fun and enjoyable, but co-op is where this game really shines.

While the game does have a few drawbacks, I'm still giving it 5 stars based solely on the fact that Borderlands is a hell of a lot of fun to play, and (in my opinion) the best co-op game out there.

This game supports 4 person Co-op, so play with a buddy or if you are a loner, like me, it'll play just fine solo

This game was really fun, hundreds of hours of gameplay, endless fun, really fun co-op, and amazing price for the whole bundle!

really great co op or single player shooter 1 to 4 people, one of the few games anymore that you can play spilt screen on same tv

This game is also a great co-op game if your looking to play with friends
