Nice for a time user.
I also hate that i don't get to move around, It's dumb how the guy is just standing there letting the very slow zombies come up and hit him, it's like he's a retard. He should be move backwards (He does do that sometimes but VERY slowly) and shoot them, and keep turning around. That's what i would do if i was surrounded by zombies, I'll look in all directions.
Unlike actual FPS's on the DS you don't get hand cramps, you can just leave you DS on a table if you want a just tap the screen. I'll probably play it when i feel like playing something but my hand hurts from playing too much games.
The Graphics aren't very good, but at least it's 3D, can't really have a 2D shooter can we? there is quite a lot of Violence so if your into Zombies throwing their heads at you or just blowing them up you might want to take a look.
As for the Story? well i haven't got that far in the game but it seems just like an average one, not very interesting. It's more of just an excuse to make a game that let's you shoot up a lot of Zombies.
I saw that it had a Co-op mode, it seems like if you know some one else with the game you can play the Story with them, i don't get how it works, if they are shooting at the same view or maybe one is viewing one way and the other is leaning against the guys back looking the other. Also the single player story makes it seem like he is the only normal Human and every one is zombies, how could there be another guy there? I might just have to play the story more further and see if the main guy really is the only one left. I think i would enjoy this game quite a lot if i had a friend i could play with since i really enjoy multilayer it makes the games i play twice as fun.
Overall this is a pretty average game, but if your into to this kinda stuff then i would recommend you take a look at it.
