Lightmare Studio makes its debut this week with the launch of Beware Planet Earth, an alien abduction-themed tower defense game for Windows.

Beware Planet Earth challenges players to protect their cattle herd from waves of cow-kidnapping aliens throughout 46 included levels. In addition to an arsenal of turrets and other weaponry, players can also attack the aliens directly with a limited-use zapper gun, adding an action element to the strategy-oriented proceedings.

Beware Planet Earth is priced at 9.99 € ($12.50). A free demo version is also available.
