Description: Lightweight and easily concealed, this submachine gun fires in long deadly bursts. Very effective against shields and biotic barriers. Inaccurate at long range. Weak against armor. The commonality of kinetic barriers has led to increased demand for rapid-fire weapons like the Tempest. Produced by Elanus Risk Control Services for the Eclipse mercenary band, the Tempest is an expensive but deadly addition to anyone's personal arsenal.
