Project EK-8 refers to mutated Flesh Raiders that were part of the individual experiments conducted by Rasmus Blys and Czerka Arms on CZ-198, a moon during the time of the Galactic War. These entities possessed the capability to generate a continuous concussive wave, and they exhibited a strong attraction towards another experimental subject known as Project TG-5. An explosive reaction occurred upon contact between the two projects, resulting in the death of both experimental subjects.
