The short version
The Bunker Spider is a web problem before it is a spider problem.
The webs slow you down, and it moves fast inside them. See the web, go around it.
What the Bunker Spider is
It is an indoor entity that builds webs across parts of a facility.
It prefers enclosed spaces: corridors, rooms and corners where it can cover the whole approach.
It is not subtle once you know what to look for. Webbing is visible, and it covers ground you would otherwise walk on.
Why the web is the real threat
Most crews focus on the spider and miss what actually kills them.
Webbing slows you. Walking through it costs speed you may need for the walk out.
It moves faster than you in its own webs. Inside the web it has the advantage, not you.
You cannot fight well while slowed. Every swing and every retreat is worse in the web.
The web stays even if you kill it. Clearing the spider does not clear the route.
That last point decides most encounters. Killing it solves the spider and leaves the problem you actually had.
Reading a web before you walk in
The web is visible if your light reaches it. Make that check part of entering a room.
Sweep the doorway with your light before you commit to walking through.
Look at floor level, not only at eye level. Webs sit across the ground you walk on.
Check the corners. Webs often start in corners and spread across the route.
If the room is webbed, take another route. That is the whole decision.
A webbed room is a room you skip. There is rarely enough value inside to justify the crossing.
What to do if you are caught in it
Sometimes you are already in the web when you notice the spider.
Back out the way you came. Do not push deeper into the room.
Keep facing it. You want to see the approach rather than discover it behind you.
Do not sprint. Sprinting in webbing does not restore your speed, and it costs you awareness.
Call for help if the crew is close. Two divers handle this better than one.
The goal is to get out of the web, not to win an exchange inside it.
Killing one, if you have to
There are routes you cannot go around. In that case, the kill is manageable.
Fight from outside the web. Standing in webbing while swinging is the mistake.
Use a shovel. It is durable enough to require commitment, but a determined diver handles it.
Keep moving between swings. It closes distance quickly.
Clear it, then still expect the web. Your crossing will be slow afterwards. Budget time for that.
Leave rather than loot. A webbed room you have just fought in is not a place to linger.
Treat the kill as opening a route, not as clearing a room for looting.
When to simply leave
Most Bunker Spider encounters should end with the crew walking away.
Leave if there is another route. There usually is.
Leave if you are carrying a full load. Slow plus webbed is a bad combination on the walk out.
Leave if the clock is tight. Fighting costs minutes you may not have.
Leave if you are solo. A slowed solo diver with no rescue is the worst version of this fight.
Spiders guard space, not treasure. The value behind them is rarely worth the crossing.
Webs on the way out
A web you crossed easily on the way in is a different obstacle on the way back.
You are carrying more. Weight already slows you, and the web slows you further. Those two stack.
The clock is tight. The return trip is when the deadline matters, and a webbed crossing costs the minutes you do not have.
You are more tired. Stamina is lower, and a slow crossing in webbing uses what is left.
Plan the route home around the webs before you go deep. Note which rooms are webbed on the way in and pick a return line that avoids them.
If the only way out is webbed, drop weight before the crossing. Shedding one heavy item is faster than fighting for speed inside the web.
Mistakes that get people killed
- Walking into webbing without looking. The light check takes one second.
- Fighting inside the web. Step out first.
- Assuming killing it clears the route. The web remains.
- Looting a webbed room after a fight. Get out instead.
- Crossing one while overloaded. Weight and webbing stack badly.
Reading it in the bestiary
The Bunker Spider is one of the 16 indoor entities in the monster database. That table lists every entity with its location and hazard rating where the source data provides one.
Many entities in our source data do not have populated hazard or health fields. We describe behaviour rather than invent figures, because knowing where the webs are is what keeps you out of trouble.
