Immune Attack is a downloadable game with outstanding graphics, detailed information, and engaging game play about the immune system.
The scenario that you will help a child with Severe Combined Immune Deficiency (SCID) by sending a nanobot, complete with probes, into her blood stream to teach her immune cells how to function again. This is immunology at the molecular level--pathogens, macrophage receptors, transmigration, and more. The immune system information is presented both in written and spoken form. It can be skipped over but not easily since it is integrated in with each mission.
This is a very large file that will take some time and storage to download and install, but that is because of it's amazing graphics. I am amazed at how much my 8 year old can tell me about immune function.
The game was created by the Federation of American Scientists. Below is the trailer on YouTube. One difficulty is that there are no instructions other than what the characters in the game tell you--and they don't tell you how to save the game. It's very frustrating having to start this complex game over again from the beginning each time!
