Welcome to INSIDER! 

-Beta-

This is a unique Tower Defense game set inside the human body. Here, you are not the hero... you are the virus! Your mission is to invade and defend yourself against the antibodies trying to heal the body. Build your defenses using different types of infections —viruses, fungi, and bacteria— and evolve to survive.  Every part of the game has been handcrafted, from the very first sketch to the final detail, to offer you a truly original and challenging experience.  Will you be able to take over the body before it's too late?
