Still this is not unplayable but only useless.YEt to find a reason why would anyone play it.People like look/rewards (thats why games like Broderlands ,Fallout and RPGs have success) and that thing is there with nothing to give you.
I beat her on elite with a Pug yesterday... props to the United Canadian Federation fleet. It was long, it was a pain, it was no fun and I'll never do it again. Why would I? you get no more reward than a Infected run that my fleeties and I can do in about 9-11 minutes.
