I don't particularly care about the ME 2 gunplay comparisons. ME 2 is the second game in it's series, AP is the first.
ME 1 had cover based shooting, and it was ****ty as hell, the sooner you ignored cover the better off you were. Even then, combat in ME boiled down to using your weapon skill (marksman and friends) then hold the Shoot button down. A.W.E.S.O.M.E.
There were much better cover systems before it too, like Gears of War or Killswitch (2003!), yet ME's managed to be crap anyway.
So if anyone wants to compare ME and AP combat, they can stick it someplace.
Good preview btw.
