In hand to hand combat, however, it uses more than the slice-and-dice technique of destruction. Beneath the horrific slashing claws rests a large mine-like globe that emits a toxic nerve gas that kills most unprotected mammals. Once the gas is emitted, it will linger in approximately a 100' area and will remain active for as long as 16 minutes. Anyone within the infected area without a self-contained enviroment will be killed almost instantly.
Since it is not alive, but a robot-like automaton controlled by the Invid Brain, it is a particularly ferocious killing machine that is not affected by gases, drugs, disease, stun blasts, or lack of air.
The sensor eye beneath one of the arms is its one soft spot, but one has to get close enough to the Scrim in order to disable it. This is extremely difficult because of the three lashing claws and the nasty spike that adorns each knee for maximum killing power in hand to hand combat.
Although not able to fly, the Scrim can run 100 mph along a level surface, leap 30' in height and length, and swim at a laborious 5 mph.
The Scrim will kick, claw, stomp, and punch to destroy its enemy. It is truly one of the most formidable opponents ever faced by REF.
