Attenuated Forcefields are a downsized shield used to protect the smaller "vehicular" units of the Scrin Reaper-17 cult. When upgraded from the Nerve Center, it grants their Shard Walker and Seeker an extra layer of protection. While active, the forcefield can absorb an EMP blast before collapsing, allowing these units to remain active. This upgrade costs $2000 and requires 1:00 to complete.
