In Satisfactory, you play as an engineer, working for FICSIT Inc. All playable engineers are female. There is no food in the game, so engineers don't need to eat to survive.

There is currently no character customization, however there will likely be some form of basic customization in the future, such as jumpsuit color selection.
Only first-person view is in current version of the game, without virtual reality support. In the future there may be some kind of top-down view for building.
As there is no food in the game, it is likely Satisfactory doesn't really have a survival aspect, other than combat.
