Immunity - Atari 2600 - Pre-Order


Immunity is currently available for PRE-ORDER and will not ship immediately. Once shipping begins in about 2-3 months, these orders will go out fairly quickly in the order received. Please contact us if you have any questions.

In 'Immunity,' you play the role of parts of the human immune system, both inside your cells, and among your cells where infecting viruses roam. Within your cells, during the “intracellular” play mode, you control the free ribosome that can shoot sideways back and forth through the cell, collecting helpful substances and fighting off the infection! When the cell is cleared of infection, your perspective shifts to an outer view during the “exocellular” play mode where you control a bound ribosome to fling antibodies at viruses before they infect your cell. When a virus is completely covered by antibodies, you direct the macrophage to gobble up the now-neutralized virus to lower the overall viral load.

Your perspective can switch back and forth several times between intracellular and exocellular as you fight the infection. If you run out of antibodies before you eliminate your viral load, you will die. But if you neutralize all the free viruses outside your cells while still having antibodies, you gain ‘Immunity!’ Along the way, you will see scoring reviews when switching between play modes.

Immunity Box


Use the left joystick to move the ribosome up/down in intracellular mode and fire button to launch sideways. You will automatically gobble up infecting RNA, Energy and Vitamin molecules, and lose spike proteins knocked loose by ramming a new virus. In exocellular mode, use your joystick left and right and use the fire button fire antibodies at the infecting viruses. If a virus is completely neutralized, press your joystick up to activate the macrophage and move it left/right to engulf the virus. Finally, press fire to dissolve the virus. The Left Difficulty Switch may be used to make the game more challenging in the A position or easier in the B position.

I picked up a copy of Immunity at PRGE 2023. It's a very enjoyable game! I showed it to a relative who is a microbiologist and she said it's a pretty accurate simulation of what the immune system does. But while you're sure to learn something, the educational aspect doesn't overshadow the FUN! Watch a demo or read through the manual to understand the details of the gameplay. I come back to this game again and again. Highly recommended.
