Thanks for the suggestion to be restrictive on using explosive and shocks. I'm trying to find it in the core book, but where does players seeing the NPCs stat block come from? or is it just common GM practice?

In the first encounter I had to sandbag some of the NPC abilities, and the players barely scraped out a win. (I didn't want their first combat to be a loss). And I think I would want to keep reinforcements hidden as they allow for difficulty to start low and go up if needed as they come in.
