Your beat-up car is specifically designed to survive those zombie onslaughts, and you’ll need to keep your finger on the acceleration button to ensure your car stays in motion. Then again, you shouldn’t press too hard on the rotation buttons. Instead, tap on them lightly to avoid the possibility of your vehicle flipping over and ending your game. Going back to the acceleration button, the only time you won’t have to press on it continuously would be when you’re going downhill.
While you really would want to let go of the acceleration button when your ride is cruising down a hill, you will want to use your boost when you’re doing the opposite – driving uphill. Your boost will also come in handy when dealing with road bumps and ramps.
Each level comes with its share of obstacles, such as barriers. You can push through them, but try not to push so hard as that may result in some parts getting knocked off your vehicle. And when you’re going uphill, you will also encounter boxes. These boxes, however, don’t contain some sort of power-up or upgrade – if you run into a box while on boost, you’ll slow down considerably, leaving you more vulnerable to zombie attacks.
You can upgrade your car in a number of ways, but the most important stats you should focus on would be those for your engine and transmission. Upgrading the former means faster acceleration, while upgrading the latter could give your top speed a much-needed boost.
When you’ve got enough cash on you, purchase a gun and equip it on your ride. And once you’ve upgraded your car’s engine and transmission, that’s when you can upgrade your guns. Upgrading your fuel tank would also be a good second priority, as that allows you to drive farther.
