Available for unlock by ECA 5-star generals, Battlefield Prototypes grants the permission to employ some of the ECA's most desperate measures by activating one of the three prototype research protocols from the Research Facility.
There are three research protocols available for the ECA general: the Manticore Protocol, the Pandora Protocol and the Venom Protocol. Each protocol gives benefits in form of new units, add-ons, abilities and upgrades that might be able to turn the tide of the battle into the ECA's favor.
Originally there was supposed to be a fourth research protocol available, dubbed the Odin Protocol. However it was scrapped due to redundancy and practicality issues.
