Game Concept to put out there for comment.

An Alien game, where the Aliens have power roles but the Town is all vanilla, except that there's Medical Supplies that act as a seer (scry if alien or not.) Envisioning two ways for the medical supplies to work
1) during Night, everyone votes for who to scry in their private QT. As day breaks, I state who voted for who and the one with the most votes gets tested: both votes and test results are public info.
2) one Town starts the game as the Medic (seer). If they die, a message appears "As XXX dies, they drop the medical supplies. Someone grabs them." and the Medic role passes randomly to another Town. (If someone is inactive, it would also pass to an active player.)

I'm envisioning Alien power roles akin to what's in the Crazy Idea, except the Mindslaver is modified (since voiding/controlling someone means nothing for vanilla town) and no Killing power (since kinda defeats the purpose of an Alien game.) Thinking mindslaver as a one-time, any-time (Night or Day) kill. Fluff-wise, basically mind-control to make the target suicide.
So Mindslaver (as above), Innocent-Looking (fools scry), a day-baner (target can't be lynched tomorrow), a role to mess up night actions (vote in #1, only works if they are the Medic in #2).

Also, general question: in a standard Alien game, is it the case that there's not a NK, but instead the aliens have an edge power-wise over the town?
