Killing Zombies
Surviving a zombie apocalypse should be easier than beating the Flood in Halo. Depending on the time of year, you can simply wait for the environment to destroy the zombies (they are rotting corpses after all). In addition, due to their ineffective mode of reproduction, biting humans (their worst enemy) -which is like fighting a lion when you want to have sex- they will be defeated quite quickly.
In addition, almost all carnivores will be eating them due to their meatness. And Americans have the highest collection of firearms of any nation, meaning that most likely, there will be at least one house on your block where you can hole up with a gun and fill any slow, ambling zombies full of lead. Honestly, a zombie apocalypse would look like Shaun of the Dead.
