Nice of ya' to add some new features, but...
Towards the end the game just takes a nose dive with the several nearly bulletproof dudes and having to pop in and out of cover like an over cafinated trapdoor-spider just to shift their kevlar asses, all of which adds up to a grinding experience similar to shoving a diamond-saw up your ass. It also doesn't help that you can't switch weapons or reload in cover either.
So the last ten minutes before you swiftly toss your monitor out the window feels like trying to eat a meat-loaf that's been streched out with sawdust from a rubber tree.
