ALL the bad guys that i kill are just freezing and some are unkillable and just walk into random parts of the screen/through the air.
So on the parts (like the battle for salvation) where it requires you to kill everyone i cant get past it. this is pretty frustrating lol.
Let me guess: you're playing it on PC.
My advice: play it on something else.
Yeah guys i am also playing this game but this game can not be save and at the end of first level my all efforts ended in smoke.
This sort of thing happened to me sometimes in TFU:USE. Exit out of the game and restart or just reload your save. It should work again.
But the patch fixes some types of errors. Just be sure you install the correct one for your region!
