The Heirotus-issue “Snow Globe” is a canteen-shaped short range electronic warfare device. It can blanket a specific frequency for a lengthy amount of time or a broad swath of the communications spectrum for a short period of time. The function and effect is somewhat similar to an Atari or 8-bit Nintendo in proximity to an FM radio. It is unclear if the device impacts Addicaine cybernetic capabilities – if it does, it would explain why Greg triggered one after running a ballistic macro.
The device may or may not interfere with Heirotus communications frequencies.
