Notes

• December 2039 is included in the first table, but the game begins in January 2040. Each table covers two month blocks.

• All months beyond August 2040 use the August table.

• All values listed above are interpreted off probability tables obtained directly from TFTD's GEOSCAPE.EXE.

• Established Alien Colonies, Artefact Sites and the final mission T'Leth have fixed crew types.

• Alien subs on Colony Supply Missions will be crewed by the same species that established the Colony, and ignore the monthly tables.

• Port Attack, Island Attack, and Shipping Lane Attack missions fall under the category Alien Surface Attack.
