Alien Zombie Megadeath

Each stage has a certain number of horizontal platforms where the player's character can run and jump around.

In Alpha stages, there is no set amount of time or enemies to spawn, putting the emphasis on survival.

That isn't the case during Adventure stages, where enemies need to be baited for collecting their crystals upon death.

Alien Zombie Megadeath received mixed to positive reviews from critics upon release.

On Metacritic, the PlayStation 3 version of the game holds a score of 77/100 based on 6 reviews.
