Electric Rake
Battery + Rake
Imagine a rake. Now send millions of volts of electricity through it and then go and poke zombies with it. Sounds like fun, don't it?
Defiler
Axe + Sledgehammer
Imagine a bat with the head of an axe and the head of a sledgehammer both positioned on the business end. Smacking something with that isn't going to leave much in the way of solids.
Claws
Boxing Gloves + Bowie Knife
These work like Wolverine's claws, without all the angst about being immortal. Cut zombies to ribbons! Wearing the hidden Blanka mask makes this even more awesome.
Tenderizers
Box of Nails + MMA Gloves
They work just like regular ol' MMA gloves (Chuck has surprisingly good Muay Thai moves), but the addition of nails make them something slightly more awesome.
Exsanguinator
Vacuum Cleaner + Saw Blade
Giant, rotating saws at the end of vacuum cleaner. Handy as it cleans up all the blood while you cut it out of flesh!
Light Sword
Gems + Flashlight
It's basically a light saber, but don't let the lawyers at Lucas Arts known that. Although a bit slow to wield, the light saber deals out tons of damage and can take out a crowd of zombies in a single slice.
Pole Weapon
Push Broom + Machete
A medium-range melee weapon that works a lot like a poleaxe, letting you slice zombies with the machete, taped to the end of the broom.
Hacker
Computer + Flashlight
This is basically a makeshift Taser which can zap zombies at very close range. Limited battery life means you're only able to zap for so long.
Ripper
Cement Saw + Saw Blade
A cement saw has a round, plate-like blade at the end, which isn't nearly as devastating as it would be if you added a serrated saw blade. Once you do, the Ripper works like a more maneuverable chainsaw.
Flaming Gloves
Boxing Gloves + Motor Oil
Having knives in your boxing gloves? Cool! Having boxing gloves on fire? Even cooler! Well, hotter. Anyway, you can set zombies ablaze with your flaming boxing gloves, and there's really nothing wrong with that.
Driller
Spear + Power Drill
Take an ordinary power drill, but instead of a normal drill bit, stick a 3-foot-long spear into it. Pokey death!
Handy Chipper
Wheelchair + Lawnmower
Most wheelchairs act as a helpful means of conveyance. The Handy Chipper…not so much. Roll this baby around, turning any zombies in your way into mulch.
Parablower
Leaf Blower + Parasol
This odd, unwieldy weapon has you sticking the bottom of a giant umbrella into a leaf blower, and jamming the other end into an unsuspecting zombie. Umbrella expands and the zombie goes poof.
Boomstick
Pitchfork + Shotgun
If your aim is terrible, you may want to consider the Boomstick. Stab a zombie with the pitchfork to keep them in place, and blast them with the shotgun to, well, not keep them in place.
Auger
Pitchfork + Drill Motor
Like a much larger version of the Driller. Imagine a pitchfork spinning at 100 RPM and imagine what sort of damage you could do if you stuck that in someone. Yikes.
Porta Mower
2x4 + Lawnmower
A lawnmower isn't the most portable of items. If only there was another handle so you could hold it out in front of you, blade part pointing straight out at your enemies. Now you can!
Holy Arms
Training Sword + Nails
There's a toy sword and shield set in "Dead Rising 2." They're mostly harmless, but if you jam a dozen nails into each, you suddenly have something that's not quite so harmless.
Paddle Saw
Kayak Paddle + Chainsaw
Remember Donatello's bo staff from "Ninja Turtles"? Well, imagine if there was a running chainsaw at each end. Suddenly Donatello seems a lot less bad ass.
Spiked Bat
Baseball Bat + Nails
Likely the very first combo weapon you make in "Dead Rising 2." Good thing it's super handy! The Spiked Bat acts like a regular bat, but it deals undeath a lot quicker, thanks to its many spikes.
