Once the Alien got on board the Sevastopol, APOLLO Central A.I. requested a comprehensive report on the station's well-being. Seegson Working Joe 937, designated as "Chuck", reported that he had "received multiple notifications of civilian trespass and vandalism on Seegson property. Since the incident, there has been a marked increase in civil disobedience."
Because of this, the various humans on board comprising the crew split into various sections and groups, and proceeded to generate significant infighting. Many groups vied for power, as they distrusted the Marshals, a group of interior security designated for the station. Throughout her travels, the various human enemies will either attack Amanda Ripley on sight or warn her off prior to opening fire if she does not move away quickly enough.
