We ran our first session the week before last. I wasn't as prepared as I would have liked. A work emergency popped up earlier in the day and I didn't have the down time I was counting on to give the module a final once over before the players arrived. Otherwise I don't think I would have been thrown off so badly by what I think must be an error.
On page 25 it says, "While
cleaning up the control room restores the
reactor relay (no roll needed), repairs still
need to be made on the outside of the ship
to reconnect the relay to the four fission
engines themselves (HEAVY MACHINERY roll and
three Turns of work). The power generated
by the ship’s four engine pods channels
through the main relay here before being
distributed to the rest of the ship."
So, I know it says that Cronus's AI eventually powers up the reactor on it's own, which contradicts the statement that the ship's disconnected engine pods provide power to the rest of the ship. And, in hindsight, the reactor is obviously where the nuclear reaction that powers the ship and the engines takes place. But my players made a B-line for the reactor room before I initiated any events, and I relied on the room description that was in front of me when they said they wanted to power up the reactor. So I told them, "The power generated by the ship’s four engine pods channels through the main relay here before being distributed to the rest of the ship," and that they would have check the engines because the relays weren't getting any power from them. Less than a shift into breaching, before any mandatory events on the Cronus, they were on the outer hull fixing the engines.
The session ended with Cham (Lucas) quietly dispatching the Abomination on the outer hull and reconnecting the engines while the rest of the crew waited on the Montero. (Rye was injured and Cham/Lucas insisted on working alone. Greed seems to be driving the rest of the crew right now, and Lucas has decided that telling them about the abomination will only encourage them).
So that puts me in the awkward position of telling the players, "Oh, actually you didn't need to connect the engines to power up the ship." Since we are two weeks since that session, it wouldn't be too disruptive to just ask the players if they would have rather have used a shift to clean up the reactor room instead of connecting the engines; except that I already revealed the abomination on the hull and the player that killed it rolled exceptionally well and is feeling pretty badass right now; so they aren't going to want to retcon that and it wouldn't be fair to take it away from them. Plus, now that the abomination on the hull is sprung, retconning it would be like putting the snake back in the can and asking the players to pretend to be surprised the next time they open it.
This throws a bit of a monkey wrench in the script, though, because the Cronus engines are online two acts early. Does Wilson even need the Montero Crew anymore? Once the AI powers up the Cronus, he could just sneak over there and initiate Special Order 966. The Cronus takes off towards Earth on autopilot and leaves the Montero behind. Game over.
