The EW-3 is a small wheeled drone — about the size of a suitcase — that carries a directional electromagnetic warfare suite capable of disrupting, scrambling, or seizing control of Brain-Computer Interface systems within a 200-meter radius. In a city where 78% of the population has some form of BCI implant, the EW-3 is effectively a weapon that attacks almost everyone simultaneously.

The disruption mode causes BCI static — visual artifacts, auditory hallucinations, motor control glitches, and sensory processing errors in everyone within range. The effects are temporary but profoundly disabling. The scramble mode targets specific BCI signatures and can render individual implants non-functional for hours, effectively blinding and deafening victims who depend on their augmentations. The seizure mode — classified, denied by Arcturus — can allegedly take control of a target's BCI and feed false sensory data directly into their nervous system, making them see, hear, and feel things that don't exist.

The EW-3 is small enough to be carried in a bag, placed under a vehicle, or hidden in a room. Its effects look like BCI malfunction — a common enough occurrence that victims may not realize they're under attack until the patterns become unmistakable. By that point, the EW-3 has done its work.
