Reaper Brain

The Illusive Man salvaged the most valuable part of the human proto-Reaper under construction by the Collectors: its central processor. This "brain" has been reactivated for use as a computational device, crunching unheard amounts of data in nanoseconds. The Crucible's engineers are dissecting the processor, working in strictly supervised, drone-assisted shifts. While direct contact with Reapers is dangerous, the engineers feel the risk is worth the potential discovery of vulnerabilities in Reaper construction.
