Running Dead is an escape/survival game in which you guide your survivor through the ruins of a town infested by zombies. There are four control layouts to choose from, but I found the tilt controls for direction and touch screen shooting to be the best of the lot.
As you run through broken-down houses, past wrecked cars and other debris, a horde of zombies follows not very far behind. But it's what is in front of you that you need to worry about most. Zombies appear in front of you often and you'll need to use the weapon at your disposal to shoot them before they slow you down. You start with a regular pistol, but you can upgrade it with better bullets and other perks, or buy bigger, more deadly guns in the in-game store once you've earned enough money. It takes quite a few plays to be able to afford the next gun up the ladder (a submachine gun), so be prepared to grind out a few levels before getting any relief.
Running Dead has a sort of 3D top-down perspective, where you view your running character from up high, but also from behind. This view lets you see the zombie horde creeping up on you -- and if they catch you, you're finished -- but holding them off is often times as easy as weaving in and out of cars. Other times, you won't be so lucky, but a couple of perks you'll find along the way will help. Boxes that give you extra bullets and coins appear randomly on your journey, but when you find a rarer blue box, you'll either get a Savior Shot or a landmine. These are special weapons designed for when the horde is catching up to you, letting you get off a blast of your gun or drop a bomb that gives you a bit more time to continue on.
Like many games these days, Running Dead lets you spend real money to get ahead; the amount of time it takes to earn coins will certainly push some people to take the easy way out. If you have some patience, you can earn coins the hard way, but you will spend a lot of time early on just going through the motions for cash.
