Illegal Alien Tower Defense

Illegal Alien Tower Defense is a strategy game about defending Earth from shapeshifting alien invaders. You play as Johnny Righteous, a mild-mannered computer programmer at the Department of Defense. After the cancellation of Sentinel, a top-secret defensive AI, you use the last copy of its code to fight back against the invasion.

Defend the daycare

Place four types of towers on designated squares to defeat six enemy classes. Keep the repatriated Day Care center from taking too many hits or the game ends. The game presents this tower defense strategy in a comedic setting.

The invasion

The invaders are shapeshifters from the third planet of a nearby star system. They consume everything in their path and seek to transform Earth; the story frames the conflict as a threat to civilization and a battle in World War 3.
