Office of Scientific Operations - Declassified Files (Release #5)

From the Office of Scientific Operations comes the following recently declassified files:File #166 ("Tarantula"): Agents Simms and Regan from the Office of Scientific Operations, the OSO, returning from the Pacific Coast having just finished dealing with yet another monster threatening the United States are redirected to a small town in Arizona to verify that a large tarantula that has been terrorizing the local inhabitants has been destroyed by the Air Force.
With Beka, a woman who insists on tagging along with the intrepid agents---a clear violation of official regulations---in tow, they quickly discover that the threat of the giant spiders in the Arizona desert are not over just yet. File #171 ("Invasion of the Body Snatchers"): The Office of Scientific Operations, the OSO, has sent agents Wayne and Wyatt out to the small California city of Santa Mira to locate a missing Air Force major, sent to investigate the impact of some meteors, and to understand the meaning of his last cryptic message to Washington.
What they find is that, while the city of Santa Mira may look like a quaint place to visit it soon becomes apparent that a missing Air Force major is the least of Wayne and Wyatt's problems. There is something very strange and deadly going on in Santa Mira. Something that seems...alien?
