Reverse Engineering and Prototyping - Xenotechnology (REAP-X) is a highly secretive subdivision of the Office of Naval Intelligence that develops technological and conceptual ideas using reverse-engineered technology from the Covenant and Forerunners. These ideas are field tested by ONI operatives.
REAP-X was formed toward by the end of the Human-Covenant war by multiple splinter groups and helped to distribute weapons and shield technology via the Misriah Armory on Mars. REAP-X expanded and began to develop new weapons and vehicles on a large scale.
- According to Frank O'Connor, the REAP-X division and the vehicles it has produced should be considered canon to the Halo Universe, though MEGA Bloks was given considerable latitude with the aesthetic design of the toys.
