Take the role of a clever commander and fight for the most precious parts of a human being. Fight for your life in the human body and enjoy this unique tower defense experience!

You are the commander of the human body´s sentinels with a clear objective: bacteria and viruses shall not pass through your defense system. The way to deal with enemy hordes is simple. Think tactically, construct and upgrade buildings, reinforce troops, support them with special upgrades and annihilate the enemy with mighty powers.

Battlefields are situated in 17 human body organs like the heart, appendix, stomach and you will fight even in the brain.

But beware! Enemies also use some tactics: Flu divides itself, Nicotinic can be invisibible and so on. Just explore and improve your fights.

Very addicting

I've been playing this game for 2 hours now. I used to play blooms tower defense, but it has nothing on this amazing game!

Extremely choppy gameplay

Decent game, but needs an update to make gameplay smooth. It jumps and skips all over my iPhone 6+. Doubt it will happen though since there hasn't been an update in almost a year.
