An Illudium-Cadmium Battery, or "I-Cad Battery", is an item found in System Shock.

It is a more powerful version of the Battery Packs found in Citadel Station. Using one will completely restore the Hacker's energy, filling the gauge all the way to its maximum value. They are not as common as their weaker counterpart, and should be conserved for only the most dire situations.


  • Illudium is a fictional element from the Marvin the Martian cartoons, who mentions the "Illudium Q-36 Explosive Space Modulator". Illudium is also referenced in the video game Wing Commander.
