Into the Dead 2

Given that the best way to survive a zombie outbreak is to run for your life, it's hardly surprising that this endless runner set during a zombie apocalypse would be instructional -- or fun. In Into the Dead 2, you have to run for your life from a bunch of flesh-eating zombies. Stopping simply isn't an option. While you can veer to the right or left to avoid being eaten or to grab a pile of ammo, you're always moving forward. But you have to watch out for those trees, which will knock you flat and turn you into a zombie snack. Also, while running and dodging the undead is your best option, you also have guns, and are a really good shot. That means you can always take out a zombie or three when necessary; just be conservative, since you don't have a lot of ammo, even after you've run over a pile of the stuff. There are also times when you'll get a knife, which you can use when a zombie does grab you, though like all knives, it's a single-use item. It's a simple idea, but an effective one, especially since the zombies seem to get in your way randomly. That said, it can get a bit repetitive after a while, and unless you have a newer tablet or phone, you'll have to bump down the graphic settings or else it'll chug and sputter on-screen like a slow train. Even so, Into the Dead 2 is still an entertaining way to kill time ... and an effective way to train for the inevitable run for your life.
