great game!
this game looks and feels like it should be on the ds (hint hint)
my only problem was killing got to be really hard and that obtaining new weapons took too many kills. the machine gun seemed to me to be alot less useful compared to the shotgun. The zombie repellent was useful as i could get 30-40 kills before i ran out of repellent which means its definitely worth buying.
The dog though useful, I couldnt afford any better dog than max which costs 100...
