There's a nice variety of guns in the game.

Bit of an odd difficulty curve. Level three is pretty hard, then the next few levels are cakewalks, then you get to a level where you have to survive for three minutes and it’s like hitting a brick wall. A fun brick wall, but a brick wall nonetheless.

It’s really rather good, actually, and well worth the launch price of 59p based on what I’ve played.

You’re a little chap with a pistol (most of the time) and you follow the guide-arrow through the levels to get to a waypoint, trying to avoid being munched on by endlessly-respawning zombies on the way. The levels are very dark, so you need to need use your torch to light them up – your character automatically fires at any zombies within the torch light.

Yeah, it's another zombie game. Don't let it put you off.

All the way it’s raining and there’s lightning, which lights up the level for a second and can show you a lot of zombies you hadn’t noticed. Panic stations and all that.

It all works – the controls are pretty much perfect – and it’s very atmospheric. Hard too, after the first couple of levels. I’m on the third level now and gradually getting better as I explore the place and find my around. (The guide-arrow points in a straight line and the maze-like city doesn’t often let you go in one, so there’s a fair amount of exploring to do.)

There’s the odd rough edge – shadows are simple boxes and I glitched through a door once – but they don’t take away from the fact that this is a very impressive game.

Don’t seem to be too many levels, but it looks like the last one is a Survival mode, which is nice – and there are OpenFeint high scores.

Given the cheap price, I reckon it’s well worth a look, based on first impressions.
