About Illegal Alien Tower Defense

Shapeshifting Alien Trespassers have invaded Earth!

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.

While the game is life-changing, it's unfortunately extremely short with no replayability. It also has maybe 3 total sound effects, so you may as well turn off the audio. $10 is pretty steep for what amounts to max one hour of gameplay.

Extremely deeply engaging storyline, with extensive voice acting, and the most realistic physics I've ever seen in a digital product! This may just be the best game, or possibly even the best singular piece of media of all time! 11/10 Would protect again!

It's not the highest quality game... It doesn't have extensive tech trees or a huge play time from what I can see, but it is extremely funny. Highly recommend for offending libtards lol!
