In Satisfactory, you play as an engineer, working for FICSIT Inc. So far all engineers seen appear to be female. . There is no food in the game, so engineers don't need to eat to survive.

Customization
There is currently no character customization, however there will likely be some form of basic customization in the future, such as jumpsuit color selection.

Speculation
As there is no food in the game, it is likely Satisfactory doesn't really have a survival aspect, other than combat.
