Well, I'll never, ever toss more than one metroid at anyone, nor will I toss one at anyone that can't stand a chance. I chose the Orks first because they're really tough and seem to be one of the most likely to figure out a way to beat them. I'm also considering tossing one at the Flood when he gets his intro up.

I'll probably make another sheet for a nation that's a bit more, well, sentient than the metroids. And numerous. I'm thinking of bringing some Crysis in if it's fine for me to make another sheet.
