If you've been keeping up with Monster Madness: Grave Danger, you know the action is coming at you hard and fast. Zombies don't think twice about ganging up on a group of lost teenagers -- let alone one or two -- which means sometimes you need a little extra to even the playing field. Well, as IGN mentioned last week, these kids are breaking out some sweet homebrew weapons in the fight against evil. Why not toss some vehicles into the mix? There are a whole slew of rides gamers will be commandeering in their battle to save humanity. Ranging from alien spacecraft to ramshackle heaps, these vehicles will bring your game to the next level. Since the goal of Monster Madness: Grave Danger is to work as a team, the vehicles can hold up to four players. They can be used in the single-player, co-op and multiplayer modes.
