Generally great scenario as a one shot but could've been written a bit better. First of all - there's no mentioning that Fermilab is an actual thing and whole holobeam thing is real. It'd be good to have some box of facts at least to dig the theme on your own. Second thing I find that all the clues could be put all together and most of them could be obtained from many NPCs so it would be easier to adapt to the group and set the flow. Having every character a list of specific clues put me off a little and in the end I mixed it up according to specific NPCs. Last but not least - there are very important stuff written in character descriptions at the end of the scenarios (like Helen's special abilities...) which aren't mentioned anywhere else. Also - this game would be sooo much better with pregens.
Again - great inspiring scenario. Took three evenings (3x2.5 hours on average) to finish.
