The game is very well implanted with the many facets of a Demolition Man commander Sheppard, after being given command of a crew of rogues of all shapes and sizes, from many corners of the known universe, in order to go on a Moby dick search, hunting party, grand voyage, aimed to control the migration of reapers - huge otherworldy entities whose influence brings great damage.
The lore speaks of something resembling Dead Space, the immortals, the eternals and Mass Effect, where you either accept a higher purpose to serve the coming of a higher power, or toil to prepare and coalesce your crew around the common goal to prevent, survive and repel the event horizon of this higher power incontrollably making an appearence and creating chaos.
This game will feature the same kind of vow, me thinks, as Goons raid her: MC can vow and toil to care for and protect Sheppard and the crew, taking upon himself the goods and the bads of his mission to prepare for the coming power, or corrupt them all for his gruesome, self centered, final goal of being a tool to whomever is controlling him.
