This is one scenario that begs for more flavour and more detail.
Down Bad has a fantastic premise and is a well organized scenario. The central conflict is well outlined, the timeline is dramatic, the external locations are well characterized. There just isn't enough of it. The NPC section, though useful, is compressed and disconnected from the rest of the action. How do those NPCs fit the different levels of the setting, specifically? The Sumu-7A Layout locations could use more texture. Maybe a small bullet list of unique things to find there or another sentence would bring them more in line with the Off-Site Locations in terms of usability.
Overall, I really like the pamphlet and look forward to running it. I agree with a couple of the other reviewers that it is begging for adaptation into a larger zine format.
