The South Tigris MoonsagaExpansion

From BoardGameGeek:

Embark on an epic journey of scientific discovery in The South Tigris Moonsaga. This expansion provides players with the means to play all 3 South Tigris games back-to-back, with special goals and abilities across each game. Moonsaga adds a solo-only 6-chapter campaign with branching decisions between each game. This campaign requires the expansions, as it will have you first play the base game then add the expansion in the following chapter. -description from designer
