I usually don't care for cover based shooters.
I really took my time through the first mission to figure out how to do it properly (I'm cover challenged... I prefer old school "run and gun")... and I gotta say... I like it.
This morning.. I found out how to change the mode to "Toggle" instead of "Hold Button"... and I think the that will make me like it even more. (Haven't had a chance to actually play the game with that setting yet).
So far I've only done the first mission after the intro/tutorial... and it's looking like a winner already. Again... I'm an old fart that is jaded and prefers old school styled PC games... but this game has definitely taught an old dog a new trick!
I'm looking forward to the rest of the game.
