What would happen if an evil spirit is raised from the dead and decides to turn everyone into zombies? Well, chaos of course. This is exactly what happens in Ninjas vs. Zombies.

One day, a modern sorcerer named Randal decides to resurrect his dead brother Eric, only to find out that he has come back evil and has the ability to steal souls, causing the people to become his zombie slaves. Randal receives aid from his father’s magic book, which tells him that the only thing that can kill the zombies and Eric are, of course, Ninjas. So now that he has turned his three best friends into ninjas, it’s up to them to save the world form the onslaught of zombie minions.

There seems to be an unusually high number of “vs” games being released this year: Stalin vs Martians, Sherlock Holmes vs Jack the Ripper, Monsters vs Aliens, Plants vs Zombies and even Kids vs Zombies.

I guess the best way to generate conflict is to simply put two forces together and let them battle it out. Many games do end up being a versus battle of sorts with your avatar taking on ogres, other player-controlled characters or maybe even just you versus the logic of a puzzle. But putting a name to the combatants gives it that sense of an ultimate death match or of a confrontation where someone must be declared a winner (and a loser).

With that in mind, here are a few of the great “vs” game titles. These might not all be amazing games but they sure have enticing and interesting names when you consider them at face value.
