Project: CRUCIBLE is a project established by the UNSC and Swords of Sanghelios which runs complimentary to the Anvil Initiative. The program aims to establish a joint Spartan-Sangheili task force of a number of disciplines and specialisations including artisan-armorers, technical specialists and supersoldiers. The hope of the program's goal is to put aside past differences and begin building a robust relationship between the two species.[1]


It is likely that Project: CRUCIBLE derives its name from the name given to ANVIL Station during the development of Halo Online; "Crucible Station".[2]
