As distinct from the "what plasmids do we know about and/or want" post already on the front page.
I was looking at the screenshot scenario contest and I realized that I haven't the slightest idea of the systems underlying plasmid use. I know there are active and passive abilities and have seen examples of each, but how is their use regulated? Do active abilities have individual cooldown times? Do they all draw from a single pool which is a. replenished over time b. replenished by Adam c. replenished by something else (commensurate with the Psi Hypos of SS2)? The game is supposed to have a survival horror mechanic of "every bullet counting" - how does that interact with the ability to spew flaming death from your fingertips? They didn't mention a limited ability to use plasmid powers in the screenshot scenario, but then again you use TK early in the screenshots to defend yourself, so why couldn't you use it until you vanquish your foe?
