All the Mindless killing doesn't seem to add up.
The absolute mindless killing is back, but a little more mindless. The battles can get repetative, and the A.I. isn't that great. All the enemies do is run towards you and shoot you. That's it.
There are some pretty cool new aspects of the game, though. You can man turrets and ride in vehicles, which simply lead to more killing. The weapon selection is pretty cool, and there are absolutely TONS of easter eggs and jokes. Sometimes pretty bad ones though. But, the bosses you will fight are absolutely gigantic! Even the sub-bosses are bigger than average.
The game is pretty fun, but as I said before, the mindless killing gets repetative.
