Main things I've notice since playing the story mode.
AI are not smart but when fighting more then 4 it gets hard.
Controls are great only thing complain about is melee messes up the next shot but I can fix that when I figure out where I should put melee
Only seen one bug when i turned a corner all I saw was a brown space picture but a second later everything popped back in.
DON'T USE GRENADES IN THE SUBWAY!
You will mess up with the ASE and switching weapons in the beginning...
Former something....
