Alien RPG: Destroyer of Worlds

I am running a cinematic one shot of Alien RPG. This is an introduction to the game with characters provided by the scenario. I will explain how the system works, divide up the characters, and we will likely complete the second act. New players are welcome.

The mission was a manhunt, the objectives clear—track down
four fugitives, recover any assets they may have made off
with, and keep ‘em all out of enemy hands. Go find them on
a frozen moon full of hostiles and get it done on the eve of
war.
Nothing you couldn’t handle.
But what it is that these bastards stole—and how the hell it
got inside them—is another thing altogether. It’s all above
your paygrade, marine—but somehow you’re the one who’s got to
deal with it.
Of course, now there’s an invasion fleet incoming, and there’s
something else, too—something much worse. Something out there
hates you—hates everyone. Something big and ugly. Something
with metal teeth—and you’re pretty sure it ain’t alone.
Yeah, the mission was supposed to be a simple manhunt. Instead
it turned out to be just another glorious day in the corps. ■
