Why? Because I'm crazy!!!
This. Is. Tower. Defense. As. Its. Finest.
Now onto the scores:
2.0 } Gameplay - This is controlled with the stylus completely. It's a drag and drop game for the most part, so there's no problem in that.
2.0 } Story - Zombies want your brain and it's up to you to defeat them with your gardening skills.
1.5 } Graphics - There are some framerates issues sometimes, when the screen is filled with plants and zombies, which I don't mind. But the graphics look really nice, but not better than the PC versions (for obvious reasons).
0.5 } Sound - Didn't care much for the music. But the character noises are a delight.
2.0 } Replay Value - You can replay the campaign mode over and over again to buy all the stuff on the shop..
8.0 } Total - A great tower defense game. Lots of charm and originality. You'll be delighted with the zombie designs and minigames.
Conclusion - "Zombies ate my neighbors"
You'll spend hours killing zombies in this great game. Use it in short burst like in a waiting room or in the bus. Have fun.
