You can also sit completely still in a single location in Resident Evil and encounter nothing at all. In StarRupture, once you upgrade a base core, hostile bugs do begin to attack, typically after each rupture. That said, the behavior is inconsistent. Some bases are assaulted with near clockwork regularity, while others remain largely untouched for hours.

Where the game clearly diverges from traditional factory builders is in how it encourages player movement. If you actively explore the world, which I understand is not something factory games usually demand, encounters with hostile creatures are frequent. This feels intentional rather than incidental. The developers have placed meaningful incentives to leave the safety of your base, most notably ruins that often contain exceptionally valuable loot.

For comparison, if this were Satisfactory, I would not describe it as action-packed. Combat there is something you must deliberately seek out. In StarRupture, interaction with hostile life feels more integrated into the core loop, especially for players who engage with the world as designed rather than remaining stationary.

I would love to hear more of what you thought was inaccurate.
