The Islands
Operation Flashpoint's three main islands, Everon, Malden, and Kolgujev, are based on actual existing islands. Everon is the Croatian island of Krk. Malden is the Greek Ionian island Levkas. Kolgujev is based on Tenerife Island, one of the Canary Islands. Another island in the game, Meganissi, the largest island just to the east of Levkas. Nogova is an island introduced in the Resistance expansion pack. While it has no real world analogue, it shares landmark names with Bohemia Interactive's native Czech Republic and several areas appear to be very similar to areas in the game.
