Came out today, and being a fanboy of the series since Pandora Tomorrow, I picked it up immediately.
Let me just say, this shit seems a lot harder than the previous ones. I'm not quite sure why - maybe because there hasn't been a new one for like ...2ish years and they don't play like regular games - but I got my ass kicked during the first mission, almost immediately. As I play more it's coming back to me, but god damn was it infuriating to go through the whole mission over and over because one guy could kill me.
No more Michael Ironside as Fisher, I believe it's Keifer Sutherland doing the voice. Not terrible, just different, although usually as you get older you get gruffer so this is kind of "why does he sound so young with pre-dominantly gray hairs?"
Got this and Payday 2 yesterday so I haven't played it much but I know what you mean about it being hard. I wanted to play a few co op missions with my brother and you have to go through the first part to get to the main menu so I set it on hard and tried to rush through the first five minutes and it took me about half an hour to do it. I got the never ending pit of doom glitch where you fall through the floor and don't die so had to restart it too. It also crashed on the cut scene just after the first part too and had to reset my xbox. At that point I was a bit worried this was going to be a frustrating game to play because of all the crashing but after that I had no problems.
Had a lot of fun playing through the few co op missions unlocked at the start. Very difficult but rewarding gameplay. Much better than games where you can just run through it with ease.
