📋 About This Mod
Ever carved out a corner of the galaxy, claimed it as your own, and then watched a parade of Teladi freighters, Split
patrol wings, and Xenon scouts wander through anyway? This mod was built to fix exactly that.
Sector Access Control adds a dedicated tab to the map sidebar where you can define, sector by sector and faction by
faction, who is and isn't welcome in your space. Set it up once and the mod handles the rest, no micromanagement
How it works
Open the map, select the Sector Access Control tab in the sidebar, and you'll see a list of your owned sectors. If you
don't own any yet — useful for a pirate or early-game run — all known sectors are listed instead, giving you full
control regardless of your empire status.
Select a sector to toggle enforcement on or off, then select a faction to define rules for them in that sector.
Rules and filters
Each rule targets a specific faction in a specific sector and consists of two parts: a filter and an enforcement mode.
Filters let you narrow which ships the rule applies to, by role, by size, or a combination of both:
Roles: Military, Trade, Mining, Construction / Aux
Sizes: XS, S, M, L, XL
If you select only a role, all ships of that role are affected regardless of size. If you select only a size, all
ships of that size are affected regardless of role. Select both and only ships matching both criteria are caught —
Mining + Size L will target large mining vessels but leave small miners and large non-miners alone. Leave both blank
to apply the rule to all ships from that faction.
You can stack multiple rules per faction per sector, each with its own filter and mode. Rules are checked in order and
the first match wins.
Enforcement modes
Expel — When a restricted ship enters the sector, the mod cancels its current orders and routes it back toward the
nearest sector owned by its faction that isn't also restricted. If no such sector exists it falls back to routing
through any unrestricted adjacent gate, and if all else fails issues a full retreat order. The ship is nudged out, not
Hostile — Restricted ships that enter the sector are immediately flagged as hostile toward the player. You and your
assets can engage and destroy them freely, with no reputation penalty. Killing them does not affect your standing with
their faction. Once the ship leaves or is destroyed its status is restored to normal.
Border Control
Each sector has an optional Border Control toggle. When enabled, the mod monitors the approach lanes outside every
gate leading into that sector and turns back ships before they pass through, rather than waiting until they are
already ins
