Or three, actually. Rose/Ross use (respectively) a fencing sabre that she shaved down to be faster, and consequently more cutty (but less stabby), and a staff pen (Complete with a stabbing-sharp Speedball No. 2 nib) which he carries everywhere. Also, 20lbs of naval brass in the form of the bell off of their grandfather's yacht. This serves half the time as an exorcism tool, half the time... not. *pushes a bell-dented Sue-corpse under a table, whistling innocently*

It is sorted by fandom and "weapon" of choice.

I've just been given a gold-plated egg whisk, and as soon as I am an agent, I plan to use it. So does it count?

This page may be a help. It doesn't include weapons that have yet to be used to kill a Sue or when such a killing hasn't been updated to the page (for example, Agent Drake's spork railgun), but there are some funny ones there.

As for questions, I'll nth the "Response Center number/names" and "Makes-Things is dead" stuff (and other big changes since TOS, like the portables portal thing). Putting a very obvious link to the Featured Agents list might help demonstrate where some of the more recognized PPC missions are and what their agents look like.

Beyond that, are there any stylistic recommendations? More places to suggest double-spacing at the end of a paragraph certainly can't hurt. The vast majority of PPCing uses third person omniscient with third person limited being in a distant second place, always past tense. I assume third person objective to be a poor idea, and past tense to be necessary for most of the mission reports unless the character wouldn't write that way, but is first person usable? Any preferred format for scene changes?

Uses a sledgehammer. It was unique when I decided on it, not sure if it is anymore.
