Immunity Invaders was a game a made with two other guys for a university assignment. Naturally, I chose to do all of the art :P

You played as a pathogen (bacteria, virus, etc.) and fought against a person's immune system. The gameplay was a top-down combat-based shoot-em-up, comparable to The Binding of Isaac.

The game was very incomplete, as none of us had either made a game before or new what we were doing. However, we had many features planned.

Before playing, you would complete a short questionaire about your hygeine, diet, how much sleep and exercise you get, etc., and the difficulty and behaviour of the game would scale depending on the results.

Many playable pathogens were planned, such as the bacteria (green guy) and virus (blue) shown here. The white guy is a white blood cell, one of the main enemies.

The mockup shown here is nothing like what the game actually looked like; it's just a collection of the pixel art I made. Some of it was very rushed :S
