Barricades can be made, it will slow the zombies down but most likely will not stop them. Grab a large item, a steel rack is best. This will take practice but drop them at the entrance of the store. Its best at columbean rostmakers or masters or the super market. Shopping carts work pretty good too!

This is an easy way to repel the helicopter, if you have the mega buster then thats great but if you don't, then use a machine gun. With the mega buster, run out from Paradise Plaza and jump on the roof of the snack tables and wait for the helicopter to come. Once its about to fly above you, shoot the bottom of it and 3-5 shots should do it. With a machine gun , you can collect them from soldiers in 8 mode. Just stock up on them and jump on top of the snack table roof and blast away at the helicopter. Now you will have an easy 20 points.
