There's a selection of combo weapons in "Dead Rising 2" that defy categorization. They're generally a little weird, a little unexpected. But that doesn't make them any less fun to use!
Drill Bucket
Bucket + Drill
It's a metal bucket with a few drills taped to the outside, pointing in. Slam it on a zombie's head and the drills will make short work of its melon. Yay!
Fountain Lizard
Lizard Head Mask + Pipe
Toss a Godzilla-looking mask on a zombie and it'll wander around, spewing flames at nearby buddies.
Beer Hat
Bottle of Beer + Hard Hat
Portable heath! Unfortunately if you drink too much you'll start vomiting. Less unfortunate: Zombies can slip on the vomit.
Heliblade
Toy Helicopter + Machete
Zombies are attracted to the noise-making helicopter. Too bad there's a giant, head-cutting blade spinning on the top of it. Set it flying and let it go to work!
Electric Chair
Wheel Chair + Battery
Don't worry, you won't be sitting on it. Mixing a normal wheel chair with a battery lets you push the chair around, zapping zombies as you roll past them. Great for clearing a crowd.
Super Slicer
Servbot Mask + Lawnmower
Unlike most Servbot masks in "Dead Rising 2," you can actually wear this one! It's got a lawnmower blade attached to your head and you can charge at enemies, taking them out with gusto.
Tesla Ball
Bingo Ball Cage + Battery
I'm not quite sure how you pick this up, but it's an electrified ball that zaps any zombies that wander past it. A ball of Death, if you will.
Burning Skull
Bull Skull + Motor Oil
Putting a bull skull on your head and charging around is ok, but it's nothing compared to setting that same skull on fire. Trust me.
Combo vehicles require that you unlock the motorcycle trailer in the campaign. This can be accomplished by completing the mission, "Here Come The Contestants."
Chainsaw Motorcycle
Motorcycle + Chainsaw
A standard motorcycle, with the useful addition of two chainsaw blades acting like wings on either side, slicing anything you drive into.
Machine Gun Motorcycle
Motorcycle + LMG
By sticking a light machine gun on the front of your motorcycle, you're able to clear the road of any potential danger. Bullets are way better than headlights, anyway.
