Christmas Versus the Aliens

An invasion is imminent, a Christmas invasion no less. Aliens have decided to give Christmas a try, and in true alien fashion, they won't bother making their own Christmas, but instead will attempt to steal it from six small towns they have targeted. That's where you come in, you and your  towers. Build them strategically, to halt the increasing waves of alien Christmas thieves.

* I don't currently have the means to add proper localization to this game, I did, to the best of my abilities, add a French and a German translation, er.. I did my best:)
