TTK is actually very good - yes initial play though is easy (due to not being able to level down to match diffficulty) but when difficulty cranks up on daily and heroic strikes it is pretty awesome. Enemies do come after you if you shoot them so the AI is pretty good. I was prepared for disappointment - got confused with the marks and light levels but now seems simple enough The foundry is huge walking around it -- and the strike in this location is worth every penny. TTK has managed to out do both Doom and AVP for atmoshphere and sweaty palm action. No running strikes on TTK and the wars in front of the breach are epic. Not that relevant to the post but nevermind - I would be p*ssed off if I had not bought TTK
