We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.
The structures/vessel has no Core (player or Alien) are considered as factionless. Some wreckage are pre-built in-game factionless structures. Anyone can claim a factionless structure by placing a core in it. Factionless structures cannot be damaged by weapon (PvP or PvE) but can be dismanteled by Remove & Repair Tool.
