All I ask of you guys is this. If and when you acquire the X-43 MIKE (microwave gun), PICK IT UP. Then I want you to point it at the first alien you see (preferably up close), and I want you to shoot it. Why?
Imagine a human-sized water balloon full of orange Jello exploding. No, better: Imagine somebody with a blood pressure of 350psi exploding at the torso, spewing guts everywhere. Now imagine it in a bipedal jellyfish. There you go.
Splat of epic proportions! Only thing more fun is doing the same to a Heavy alien trooper. Biblical gore.
