This is difficult to admit: Sometimes a firearm alone, or even a full arsenal, will not suffice for eradicating zombies and surviving the zombie apocalypse. When things get super nasty, you must be prepared for close-combat defense with a blade. Like guns, there are plenty of knives and uniquely wicked cutting tools on the market. The zombie hunters at Outbreak:Omega 5 carried a terrifying blend of zombie-slashing tools.

Here are the Top 5 Backup Zombie Weapons from Outbreak:Omega 5:

The Bayonet

Practical and efficient: two keywords for surviving a zombie onslaught. The simple exchange of a gun for a blade can be a life-threatening matter of seconds. With a bayonet, you're ready to back up your empty magazine instantly with a second line of defense.

The Tactical Tomahawk

Every zombie hunter needs a hatchet or tomahawk. Not only is it good for reasonably long reach to eliminate zombies, but it's also a great survival tool. On top of that, if you're really skilled, you can throw it and take zombies out at even longer distances. Just watch "The Last of the Mohicans" for expert training on tossing a mean hawk.

The Long-Handle Machete

This weapon makes the list for several reasons. It looks sweet; the handle allows for two-handed powerful swings; it's long enough to slay zombies at very safe distances. If a zombie hunter needs to shack up in the bush, this machete is also perfect for hacking out a solid trail and materials for a shelter.

The Punch Blade

This blade may have "cool" appeal to it, but it's down here at No. 4 on the list because it's dangerous for the user/zombie hunter. Why? Any blade that requires the hunter to get too close to a hungry, infected zombie is only suitable as a last resort. Stick it in your boot and use it if you're pinned down, but only after you've run through all the rounds in the revolver that was strapped to your ankle.

The Zombie Cleaver

Unless this backup weapon is totally razor sharp, its reliability is minimal. Reaching a zombie's brain with a straight blade with no pointed tip could be very difficult (just maybe not for this guy, but we're not all built like the Terminator). However, when the going gets tough, the tough eat zombies. That's right ... if you run out of survival food you might get stuck eating zombie parts. Hey, every zombie hunting camp cook needs a cleaver.
