Spy Games
Four spies from MI6, the United Kingdom’s intelligence service, were sent out to record activities at four
locations in four countries near the Caspian Sea. They set up stakeouts at an embassy, a nightclub, a
prison, and an island compound. They were each armed with a different remote control vehicle and had
different cameras (night vision, low-light, 100x zoom, and thermal) to complete their mission.
Figure out which country each spy went to, along with the location they were monitoring, and which
camera they used, mounted on which remote control drone.
» The island was being scoped by the R/C boat, but
not with the night vision camera.
» When the spy who had the R/C helicopter realized he couldn’t get close enough to the dance
floor, he used the 100x zoom camera.
» The embassy being watched was located in Azerbaijan. Agent 005 was not in Kazakhstan.
» The thermal camera was used on the prison, but
was not mounted on the R/C car.

» Agent 007 went to Uzbekistan, but was not
controlling the R/C car. Agent 004 was scoping out
the club.
» Agent 006 was not in Tajikistan. He was scoping
the island compound, but not using the R/C plane.
» The embassy was not being monitored with the
low-light camera.
