The Shrieker is a small unusual enemy capable of floating indefinitely in mid-air. They float around the battlefield in large swarms with modified Gorgon Burst Pistol for weapons. As they float around, they emit a shrill shrieking sound which is where they get their name.
They can't take very much damage (though more than you'd think) before they die but this just presents a new obstacle. Upon death, the shrieker will set a course to try and crash into you before exploding on impact. In some cases, careful manipulation will allow you to cause several to collide and explode, thinning the pack for you. Easily the most important advice when facing Shriekers is to not get over-confident. While they aren't particularly dangerous alone, getting caught in the middle of a swarm can be deadly.
