What's the difference between the three dlc in Titan Mission?

Different skills and different DLC points are different, which should be calculated according to the specific plot. The protagonist has different endings, and different versions of DLC have different endings because of different main tasks.

The three DLC are: the underworld plot, the Yate plot and the northern plot.

Titan mission DLC is an expansion, and the newly downloaded expansion is the follow-up content of the game update.
