Dead Trigger 2
Dead Trigger 2 is one of the most popular Android FPS games to date, and with good reason. The gameplay is addicting, the graphics are simply unmatched, and are even better on NVIDIA-powered devices. You'll love the lifelike physics, active lighting, and exceptional detail.
With 40 million people left on the planet and killer zombies walking the street you'll have an arsenal of high-powered weapons to fight off the hoards. You can unlock additional weapons, like a chainsaw or Gatling gun, or buy weapons with real money if you're impatient.
With an evolving storyline and continuously being updated with more content, this is one of the best games to download. It's also one I show off to friends or family to showcase Android gaming graphics. Be careful though, it can be so addicting you'll find yourself spending money on more weapons. The developers have a new game called "Unkilled" worth considering too.
