Admit it, you’ve suspected that they walk among us. Aliens can appear in any part of the city unannounced and uninvited! And they do not play by the rules! They can abduct your Urbanites and take them hostage.
Watch your cities get infected with these little green maniacs who seem to teleport across the map and show up just where you least expect them.
Take me to your leader! Urban Insanity has just gone interstellar!
