Burn Zombie Burn is practically the definition of "casual game."
Clear rules: kill all the zombies before they eat you.
Simple controls: a top-down point of view, as you run around and shoot stuff.
True to theme: while the shotgun and uzi are the simplest to use, the chainsaw and cricket bat are far more rewarding.
A twist: zombies are afraid of the burning torch you can brandish ... but if they catch on fire they fearlessly sprint towards you ... BUT point values are increased while there are zombies buring.
It's perfect for killing time (and zombies) between loads of laundry. A couple rounds coincide nicely with the wash cycle. And the price is right -- one roll of quarters!
