I love a good frag fest :D
An excellent game, and another brilliant iteration of the zombie killing theme, although I think I like this more than The Last Stand due to the amount of freedom, powerups, and crazy weaponary.
Firstly, the graphics. As a top-down view game, it's pretty good, but the amount of corpses, blood and bullet casings that pile up is amazing. You can tell where you've had the most action, and where you've been having some re-action as you see everything get buried under the entrials of something else. A good variation of enemies, I'm just a bit disappointed Laser Cannons seem to eject the same shells as shotguns.
The sound was decent, ambient evils gently screaming in the background whilst explosive gunfire and creature noises envelope the rest of the audio atmosphere. Good stuff overall, just nothing that extremely grabbed me.
I didn't get further than halfway through the second day mind, because I managed to stumble upon the massive exp glitch. I was only testing the Laser Cannon too x-x It's a shame.
I think the weapons are pretty balanced, all apart from the damn starting pistol. 6 seconds to reload?! Even in Hollywood slo-mo it doesn't take that long. I know it's for gameplay purposes, but IMO it detracts from it since most people know pistols to be weak but at least averagely quick reloading weapons.
Before the glitch, my favourite weapon was the FAMAS. I loved how I could use it most of the way into day two with the Power Ups, if I wasn't hit by the glitch I'd probably have saved up for top Light Machinegun or the Jackhammer.
I didn't try Survival, I'll do so later. But as a review based on the main game, I think you earn a well deserved 10/10 and a 5 from me. Hope to see more soon, this is probably one of the best games to hit NG in a long, long time.
