Alien Havoc is an action-adventure game for the PlayStation Portable that pays homage to classic arcade titles. Players control a small alien tasked with abducting cows from Earth farms while evading hostile farmers. The game features intricate farm mazes, stealth mechanics, and various throwable items, such as vegetables and rocks, used to fend off farmers and ensure successful cattle retrieval.
Alien Havoc is a throwback to the classic arcade game genre, putting gamers in command of a little alien who must pluck cows from farms on Earth, load them onto his spaceship, and bring them back to his home planet. The farmers, however, won't let their cows go without a fight. Players must tackle wrapping farm mazes of confusion, play hide and sneak under the cover of tall grass, and throw veggies, rocks, or whatever they can get their alien claws on at the farmers as they fight to bring these valuable livestock back to their home world.
