i bought this when it came out and there were no players then. i was lucky if i ever saw more than 3 players waiting to play.

terrible terrible terrible idea by 2K.
no wonder Levine's body language screams "don't fucking look at me! this was NOT MY IDEA IN ANY WAY whatsoever! blame the morons at 2K!"

they should have used a co-op/bots option. surely the morons who wrote this tripe would've figured out this was never ever gonna grab the COD fanbois away??

kinda reminds me of Boredomlands 2... basically a giant DLC for Borderlands 1.. with more 'stuff'

BS2 is just a giant DLC for BS1. lame LAME story, same combat in every respect
