I think they went a touch overboard, I have spoken to a few of my friends who play and they all seem to agree that it is just a touch over the top. I have only tried it three times (Several hours) but three separate groups and we get to the point of dismantle mines and during that phase we end up dying. Please no cheese guides I really don't like using them, I want to beat it in a legit way. Can I say I have never used a cheese? Nope but it is something I RARELY do.
