I like the design and concept and that you present two ways to tackle the investigation, though I would like a little more info on each method. The way you handle the swarm mechanically is solid. I think you incorporated skills well and areas have decent interactivity. I also like your art and would like to see more of that, maybe with a little more polish. The red herring of the marks on the walls is fun, but may be mentioned too much, since it's ultimately a dead end.
I think most of the criticisms of the module would be resolved by more proofreading or editing. There are some misspellings and some issues rearranging the text would resolve.
As I was reading, I kept feeling like I was missing pieces of information, though I was able to put the pieces together afterwards. Some examples:
- The very first sentence says "The Ohm 64 mining site lies near the slums," but I don't know where this is. I see under warden's notes you say it can be set in any location, so maybe this information could be rearranged to avoid confusion. Since the slums don't seem to come into play at all, you probably don't need that part.
- Then on panel 2, you say the player can approach the investigation in two ways "discrete or official. Officers have more authority if they go the corporal way." I am assuming that officers are the official way, but do you mean to say "corporate" instead of "corporal?" This could be tightened up to be more clear.
I'm not sure what the end condition of this module is, or how players would know they're done. There doesn't seem to be a final encounter or proof of the cause of the productivity decline that can be taken to the corporation. I can see the players encountering the swarm once and assuming that's enough proof.
