Fall of Reach - Mjolnir Upgrade

“There is a new layer sandwiched between the reactive circuits and the inner biolayers of your armor,”
Dr. Halsey explained. “It is a weave of additional memory-processor super-conductor.”

“The same material as an AI’s core.”

“Yes,” Dr. Halsey replied. “An accurate analysis. Your armor will carry Cortana. The MJOLNIR
system has the nearly the same capacity as a ship-borne AI system. Cortana will interface between you and the
suit and provide tactical and strategic information for you in the field.”

“I’m not sure I understand.”

“Cortana has been programmed with every ONI computer insurgency routine,” Dr. Halsey told him.
“And she has a talent for modifying them on the fly. She has our best Covenant-language-translation
software as well. Her primary purpose is to infiltrate their computer and communications systems. She
will intercept and decode point-to-point Covenant transmissions and give you updated intelligence in
the field.”
