Missile barrage - Bombards the target area with volleys of missiles, dealing damage to all objects within the blast radius.
Phase Missile Swarm - Launches a large volley of phase missiles, hitting multiple targets simultaneously.
The missile barrage lauches multiple volleys and targets every enemy within the blast radius, phase swarm launches one big volley and hits a few. I think the part that suggests it attacks everyone is the "to all objects within the blast radius".
