Illegal Alien Tower Defense
Good game, but it sits 100% of the way from its all-time low to full price. It drops harder in seasonal sales. Patience pays.

About this game
What this game is, in the developer's words
Can you save civilization from the brink of collapse, and restore Earth to a High-Trust society? This is a Tower Defense game focused on strategy, tower placement, and defeating enemies in a hilarious setting. Warning: Mature content. Depicts violence, cartoon blood, and macabre comedy.
Their vile species, known as "Third-Worlders", hails from the third planet of a nearby star system, and have now unleashed their rampaging hordes, consuming everything in their path, seeking to turn all of Earth into a dumpy Third-World Hellscape!
You play as Johnny Righteous, a mild-mannered computer programmer working at the Department of Defense on a top-secret Defensive AI, known as Sentinel, before it was mysteriously cancelled. Now, using the last copy of Sentinel's code, it is up to you to turn back the tides of the invasion.
Can you save civilization from the brink of collapse, and restore our High-Trust society?
Or will evil Alien Shapeshifters win World War 3 by waging a Third-World War?
This is a Tower Defense game focused on strategy, tower placement, and insufferable enemies in a hilarious setting. Use the designated squares to call in 4 different types of towers, with one type being upgrade-able, and defeat all 4 different enemy classes that you encounter. Just don't let our repatriated Day Care center take too many hits - or it's game over!
Any resemblance to people living or dead are purely coincidental - you're fighting shapeshifting aliens after all. Remember that this game is a fictional parody, and purely for entertainment.
Warning: This game displays Mature content, including violence, cartoon blood, and macabre comedy. Anyone sensitive to these mature topics should consider this before purchasing.
