Disappointing.
I played the first one, and beat it. It was totally an awesome game. I was hoping this one would be as good, but no such luck.
I only have two complaints really.
#1: I decided to play on mortal a bit to get used to the controls. Mortal sounded like the easiest to play as. I played about 5 times, first time I killed one before I died. The second time two. Then two the next two times and finally, I discovered that with the non-sword weapon (2) I could back them into a corner and just slash like mad. I killed like 10. Then the explosive guys showed up and it became impossible. For being on the easy mode, I sure don't want to know what the other modes are like. "Quite hard" shouldn't mean impossible. I'd also like to point out that the most effective attack was button mashing... not even more than one button. I also managed to get Absolutely Blood Thirsty doing that as well, but it didn't matter since no matter what, I died.
#2: My character fell through the floor on the first spawn one of the times I played. Then, suddenly reappearing directly in the path of a knock-down attack really put me at a disadvantage.
Overall, I'm sure it's a great game, but there's no point in it being a good game more than 1/20 of the levels if the first level is essentially unbeatable.
