I host one. I call it "Space Navy/Army RP".
It's about this alien invasion on Earth, led by a large army of war-bound Mutalids, accompanied by some big, ugly bugs.
You are a member of the QRAD: Quick Response Alien Defense (Or QUAD for short). It's objective: defend Earth from any extra-terrestrial invaders.
I host it mostly in the mornings, but I'm planning on hosting it in a few minutes.
