Okay, so I just finished my first 5 minutes of gameplay, and here are my thoughts:

1: The feel of the game is awesome so far. The charge up attacks, and the effects of the special moves really give you a sense of power. I love charging up my attack and seeing zombies explode everywhere. (The blood spatter helps this a lot). So pretty addictive combat so far! Love it!

2: I think you're start up tutorial is a great idea. By the time I finished it, I had a grasp on the basics of the game, and it kept me entertained.

3: I am still scared about the energy, but need to test this further than 5 minutes.

FUN SO FAR!
