In a world crawling with undead, it seems the opportunist is alive and well. A bespectacled Los Angeles film director wants to make zombie films, and he needs a murderous star. Enter your broad-shouldered, square-jawed avatar. Zombiewood is, through and through, a twin-stick shooter. One virtual analog stick dictates movement; the other controls which direction your hot lead flies. Using pistols, machine guns, flamethrowers, and rocket launchers, you’ll mow down hundreds of zombies as they vie for your noggin.

Beware playing O. with anyone who's aggressively competitive. This minimalistic orb-grabbing game has the potential to bring out the beast in even the most docile opponents. Games may start off friendly enough, but when it gets down to the wire, smacking hands, flicking fingers, and wrestling digits is par for the course. You might just find yourself declaring a thumb war... or worse.

If you ever wanted to see how the pairing of minimal effort and a free-to-play model could decimate a play experience, NFL Pro 2013 may be the greatest example to date in any genre. It's a disaster in nearly every respect. NFL Pro 2013 has the real-life teams, but not the players, stadiums, or schedules, instead substituting laughable fake names and generic faces for the identical-looking player models. But that's not nearly the worst of it. As a wildly cynical freemium offering, you'll have to use your limited in-game currency to purchase even basic plays in the middle of a game.
