Alien Terror, Retaliation and Supply missions are special cases and are not present in this array since those missions are automatically generated. The random missions assigned to each region can be of 5 kinds: Alien Research, Base, Abductions, Harvest and Infiltration. The game will create an array of possible missions for each region of the world to be used when randomly selecting missions for each month.
The detection chance for Retaliation missions is given by the formula: (completedFacilities / 6 + 15) / (mindShields + 1).After The Martian Solution is researched OR depending the difficulty level (March 2000 on Easy or November 1999 on Superhuman): 1 Alien Retaliation mission is added, in addition to the above.There can only be 1 active Retaliation mission per region.If this fails the aliens will assign the Retaliation to a likely point of origin of the interceptor, based on its approach vector The chance of the Retaliation taking place in the region of the shootdown is determined by the formula (50 - 6 * getDifficult圜oefficient).Starting on the first month, each shootdown of a UFO can trigger a retaliation mission by the aliens, with the chance being determined by difficulty level, at Easy being 4%, then increasing each difficulty level by 4%, until it reaches 20% on Superhuman.Once an Infiltration mission starts on a region it will repeat itself indefinitely on that region, and it will keep spawning bases after all countries have signed pacts with the aliens.July, 1999: 2 random missions, 1 Alien Terror.
February to June, 1999: 1 random mission, 1 Alien Terror.January, 1999: 1 Alien Research on the region of the initial XCom base, 1 Alien Terror.The aliens will generate new missions each month according to the following pattern: Alien Missions Generation Mission Frequency
