Udder Chaos

In Udder Chaos, aliens invade Earth and try to steal their cows. Of course the player can't stand for this and uses a gun (only the crosshairs are visible) to protect the cows. The game is played on a single screen and aliens enter it. If the player does not manage to kill them with rapid button presses, they use a teleportation ray on a cow and try to leave the screen. The game is lost when all cows are gone. Appearing bonus items should also be shot in order to earn advantages like a powerful smart-bomb which clears the screen from all opposition. There are also some other enemies with special powers, e.g. a robot cow which shoots milk and covers the player's view.

The standard wave mode has twelve levels with increasing difficulty. Each kills earns money which can be used to purchase upgrades (shot damage, shot spread and rapid fire) before the next wave is started. The other two modes are endless (upgrades are earned over time and the game continues until the player is defeated) and kids mode (aliens die after one shot).
