Notes
- The first appearance rate block includes December 1998; however, the game starts in January 1999. It is included because the tables cover 2 month blocks.
- All rows except Alien Terror are unused in the January table; the non-Terror mission for January 1999 is hardcoded to be a Sectoid Alien Research mission in the same zone as X-Com's first base.
- All Retaliation rows are unused. Retaliation missions triggered by shooting down a UFO are performed by the race that crewed the UFO shot down. Scheduled Retaliation missions at the start of the month are evenly distributed among the races (20% each), regardless of month.
- All months beyond August 1999 use the August table.
- All values listed above are interpreted from probability tables in GEOSCAPE.EXE.
- Alien bases will appear upon completion of Alien Base and Alien Infiltration missions. Interfering with the mission will delay the base's appearance, but cannot prevent it. They will be crewed by the same race that performed the Alien Base or Alien Infiltration mission.
- Alien Supply missions will always be crewed by the same race as the base itself.
- The Cydonia mission has a pre-defined crew setup.
