Unofficially known as the "Rusyana," the Kisaragi Prototype was a new AC designed by Kisaragi and is seen in Armored Core: Nexus.


Kisaragi Protoype


Most likely built as a next generation Armored Core, the Kisaragi Prototype is a high mobility unit with impressive capabilites. Its design suggests the AC is equipped with high speed hover type legs. For weapons, it had a pair of pulse rifle arms, shaped like wings and unique head style; despite its capabilities, its durability was considered poor for an AC. It appeared first in "New AC Performance Test" and again several times outside of the development training room but was discontinued by Last Raven as a result of the perceived poor performance of the unit (attributed mainly to the fact that most were destroyed by the Raven). The unit for the most part is custom, and only its core can be obtained.
