What is the best way to kill zombies in deadrising?

to get alot of kills get to the maintance tunnel and right before u go in get the red car and also look for a big truck u can get in the gun store is in the place near seons food store check ur map ull find it (if u dont know ull have to fight a boss stand behiend the mag racks and try to get him from afar) bring food items for both situations
