Sounds like it's going to be a legacy game:

During the co-op game for one to four players, the group can experience a narrative-driven campaign that will enable players to explore different storylines and outcomes depending on their choices. As their chosen characters, players can upgrade their unique abilities by spending the experience points they gain, as well as unlock new powers through optional loyalty missions. The group can also improve their various pieces of equipment and weapons as they advance through the campaign.

According to the game’s publisher, Modiphius, the narrative choices made by players will have consequences further down the line, with there being potential for multiple playthroughs resulting in never-before-seen experiences.
