Story Events in Halcyon 6 can be triggered in a sector when the player achieves certain criteria within that sector.
A super simple example of "criteria":
- A player controls an asteroid sector (criteria 1) with a fleet which has a talented engineer (criteria 2) commanding it. That fleet has a dreadnought with a tractor beam (criteria 3). This triggers an event whereby the engineer recognizes an interesting asteroid rich in a particular Resources type, allowing the player to try to harvest it.
As the game progresses, the player will extend their reach across adjoining sectors. Eventually, though, the Chruul will take notice, and will begin expanding towards the station, claiming Star Sectors as it goes. The player might be able to hold them back for a time, but eventually the Halcyon 6 station will be surrounded and the game’s final battle will ensue.
