Program 341 Predator

Devised as a counter to Spartans as part of their planned conquest, was intended to be a generic range of augmentations that could be applied without concern for species specific rejection. As it was intended for Sangheili, jiralhanae, and Kig-Yar as a broad spectrum of augmentations, it focused on surgical and cybernetic upgrades, rather than chemical or genetic. augmentations included muscle and skeletal enhancements, sensory upgrades, improvements to healing, and augmentations that altered brain function to enhance combat speed and problem solving. While lacking compared to the focused Spartan augmentations, they enhanced the combat capabilities of their subject to unheard of levels.
Ultimately, while successful in it's goal of augmenting individuals, it did not close the strategic gap between Spartans and other augmented personnel, lacking many further refinements, such as MJOLNIR, training, and further advances.
