The levels in ZombieSmash! are relatively quick and the game saves automatically, so it is a good pick-up-and-play-for-a-couple-of-minutes title. And, if you're only playing a level or two at a time the frustrations are kept to a minimum.
As we inexorably head towards the zombiepocalypse, we're going to need to become more comfortable detaching body parts from the undead and watching the resultant splatter without a sense of squeamishness. ZombieSmash! will only help people do this, and the ability to freeze frame, save, and upload to social networking sites the final zombie death on each level, can be most amusing as well.
If you're just starting out your own preparations for the end of days and looking for a low-key way to desensitize yourself to zombie death, ZombieSmash! is a great place to start. More experienced zombie killers will also find new thoughts on how to eliminate an oncoming zombie multitude. The game may not go as in depth as some of its console relatives, but it is a satisfying on-the-go study aid.
ZombieSmash! is not rated by the ESRB but features cartoon violence.
