The RollerHawg isn't the most subtle of beasts.

It's no Wolf Dozer, but still...

Why mow down zombies with a boring old motorcycle, Lambourghini or bulldozer, after all, when you could spice it up a little? Combo vehicles work in much the same way as combo weapons – find a blueprint that lets you mash two things together to make them even better.Take the RollerHawg, for instance. This is what happens when you grab a motorcycle and a steam roller and put 'em together. In short, it's a rolling wheel of motorcycle-powered death with spikes and twin flamethrowers. If you saw yesterday's bad-ass CG trailer (above) then you've already got a fair idea what this vehicle is about – turning crowds of zombies into a fine red mist – and that's exactly what it's like when you're behind the wheel. I was pointing it straight at the thickest knot of zombies in sight and sluicing through them. Any stragglers? A few blasts from the flamethrowers sorted them out.Combining vehicles is as easy as combining weapons. Simply take one vehicle and drive it near another. If there's a combo you can activate they'll both be glowing. Two button presses later and you've got your combo vehicle. As mentioned, you'll need to find blueprints for each combo, but once you've created it once out on the streets, you'll then be able to spawn the vehicle out of thin air from the game's garages.Much like the weapons lockers - which let you create any previously-created combo or found weapon - garages do the same thing for vehicles and vehicle combos. It's all about letting you play with the weapons and vehicles you want, without a whole lot of legwork. Of course, there's a cool-down system so you can't go too crazy.The Roller Hog wasn't the only combo vehicle we got to try out today. The Junk Car fires cannisters of noxious gas, as well as explosive propane tanks. Best of all, however, players can set it to self destruct. A crowd of zombies ahead? Gun it towards them, activate the self-destruction timer and bail out.There's a heap of these combos. Combine a forklift and a fireworks van and you've got a ForkWork, aka an explosive death machine with a boost attack to skewer zombies with the forklift's prongs. Or how about the Shock Dozer? Take a look at that bad boy...Each combo vehicle is designed to support co-op, so there'll always be two seats, as well as a secondary attack for the second person. It's also worth mentioning that the vehicle combos utilise a similar category-based system to the weapon combos.Just as you can swap in a weapon from the same category (say, a broadsword for a samurai sword) and still craft the combo weapon you want, the same applies to vehicles, with a bunch of categories covering off size, type and so on.Combo vehicles are another cool inclusion in a game that's aiming to give players an expansive zombie sandbox and all the tools they need to exact bloody, over-the-top revenge. Will it all come together? We'll find out when Xbox One launches later this year.
