I'm prepping this scenario to run, and I was surprised at how little energy there was at the ending. The energy shield collapsing event feels cool but I'm not sure it'll be impactful or exciting on its own. Also, the drone attacks seem pretty random, especially considering the players might not even be going to another tower. Plus, it's pretty disappointing that there's not more of an event around fixing the tower or escaping to your ship. It feels like there's a missing encounter.
I'm thinking of just combining the two last encounters and the conclusion. So the players will be doing something to repair the tower (likely checks at relevant computer terminals) while shield shards are falling around them and they're being attacked by repair drones. Or if they decide to head back to their ship, have them do something similar to help the ship escape while still being attacked by shards and drones.
Am I missing something though? I want to give the scenario an honest try, and I like the stuff in the first half, but I'm wondering if there's something I'm missing or if it really does end in a whimper.
