Zombeast Stampede

An uneasy mission lies in front of you. You put yourself at the mercy of zombies. The situation is different here, no undead people, but ugly animals wanting some meet. They attack in waves and for example zombie kangaroos jump so well, that they avoid well aimed shots. Elephants use their trunks as pistols making them very dangerous foes. Each wave brings new difficulties but with every appropriate upgrades you increase your chance for surviving.
