I viewed the campaign as a matter of initiative. If Venus tier was about discovering just the hell what was going on, Luna tier was about the PC's moving from reactionary to proactive action. Basically, I play a group of opposition NPC's against the PC group all the time. For the first three tiers, my only rule was that the two groups never really meet outside of dealing with the fallout of the other's actions. So, in Luna tier, the opposition had no idea Artemis was going to make a very bad choice on Mitre, and the presence of the PC's was initially thought to be in relation to the Professor Truth interview and not previous operations. By the time the opposition connected the Mitre operation to the Venus forks and took them down, the PC's were already gone from Mitre. The opposition was equally ignorant of the Exsurgent risk in the Lunar tunnels and the retrieval of Artemis's ecto. The Clever Hands job appeared to just be Preston keeping his cover. They left no traces of espionage activities on the base itself, and their stealthy resleeve of Nissim meant any evidence of their trip to the Cognite bunker was covered up. So the intel discovered at Clever Hands and the bunker never factored into opposition planning either. The Firewall interference at Necter was obvious, which is why the bounty on known quantities in the team (namely, Gerard) was up'ed, leading to the attack on the scum barge by Bohimi Eshuabay. Still, this appeared as anti-Oversight interference by Firewall, and there was as yet no evidence that the true Know Evil plot had been discovered. Opposition thought Firewall was just chasing its own tail. Finally, the PC's presence at the PCR was completely clandestine, as was Yu-on's strategic betrayal of Manjappa. The opposition had no idea the Firewall team had gotten so far in their investigation, and so they thought the Haunted Stars remained completely undetected. Had PC's attacked the plot points in a different order with different results, I'd of played the opposition team's actions in my head differently. As things worked out, they pulled off the heist while imitating the Haunted Stars plan, and they exited the habitat with enough stealth to fool the opposition. If they had failed, their corpses and stacks would have revealed that the team knew all along about the opposition's movements in the Luna system. This would have meant the opposition would have reassessed Firewall as a much larger threat and acted accordingly. The attack on the resleeved agents by the opposition would have been the opportunity for players to re-enter the story had the bank heist not gone well. So, the recent Hotel California kerfuffle bought the players a big lead on the conspiracy's motives, and they have begun investigating on Vo Nguyen. However, the firefight and death of all the agents sent to Hotel California has alerted the opposition that someone is close on their trail. Firewall, and specifically Preston's team, has become a major threat. They have lost the initiative, and future adventures will see them in the reactionary position again as Manjappa (e.g. me) makes moves against them. Basically, if you are running a espionage/conspiracy game, you have to ensure that ever major success/failure moment in the campaign has an option where the PC's successfully chase the conspiracy, and an option where the conspiracy successfully chases the PC's. This keeps the game moving regardless of success or failure. Sorry if that was cryptic; things will be more clear once the campaign wraps up.
