Any fishery directly targeting forage species, including the herring and menhaden that supply lobster bait in New England (an important industry that is worth $500 million annually to the local economy), must proceed with great caution to prevent putting too much pressure on the delicate food web.

|
If those late-game adversaries feel futile, like little more than obnoxious speedbumps, then that's entirely in keeping with where you are in the "food-web" aboard Talos I. It's why the game's title ends up being more than just an awkward tie-in to an abandoned IP. The question of where you sit in this ecosystem, whether you can cross the predator / prey divide, is the question that this entire game has been trying to answer.
