Zombies vs Penguins 4

Penguins look so lovely that hardly anyone would believe that they are able to actually do a harm to someone. But when it comes to zombies, they do not hesitate a second. They turn into killing machines leaving nobody alive (do not worry guys, this happens only when a zombie is around, so you are safe). And here we go, first zombies are coming to the range of few penguin officers. They grabbed their guns and began their hunting session. Shoot all zombies and try to collect all stars for perfect gameplay. Have fun.
