Giant Spider
Access: None
Additional Access: Wherever you can smash your way into
Difficulty: Easy to Medium
Supervisors: The Broodmother, or xenobiologist that made your Broodmother sentient.
Duties: Hunt down those carbons and make massive nests of webbing.
Guides: This is the guide
Quote: Good luck, I'm behind 7000 webs.

Giant Spiders are the worst thing a traitor xenobiologist can release, their sheer numbers and strength alone are enough to overwhelm an entire station. They can also be spawned into maintenance by a mid-round event.


Generally spiders move at a normal speed while in webbing, but are slower outside of webs with some exceptions (scout and viper)

Giant spiders immune to temperature damage, allowing them to survive in hazardous places. These spiders cannot be seen in-game outside of divine intervention.


This is a baby spider, created by egg clusters, hydroponics trays, or strange alien organs. They have a low amount of health and they move around fast, and are sometimes player controlled. They will run around for awhile until they grow into a big spider. They can and most certainly will use vents, so they're very good at not getting killed.

So you're a spider

It seems science has gone too far! The spider will, depending on it's type, either go around killing, or laying eggs for the next generation of killers, or both. Some are better at the former, and others are better at the latter.


Spiders are weak alone and thrive on teamwork there are plenty of strategies you can follow to increase the chances for the colony to survive.

Spider Strategies Team Strategies
Nurse Spider
  • Your flesh is weak, but it's not your strength that matters but your capability to heal others. Stay near stronger spiders to heal them, and use them as a shield from incoming enemies.
  • Webs allow for other spiders to reach battle faster and increase the safety of the nest. Expand the nest while danger is low.
  • Base building with a team of Tangle Spiders - Expand the territory while they make stronger structures to reinforce it.
  • Help your fellow Nurses - Though you can't heal yourself, you can heal each other. Nurses can try to stay near other Nurses in case anything goes wrong.
Tangle spider.png
Tangle Spider
  • You are a living fortress constructor. Fortify the fort and stay out of enemy sight. Let the traps take care of any careless intruders.
  • Although you deal low damage, you deal high structural damage. Use it to destroy doors to build web passages for other spiders.
  • You are able to patch yourself up back to full health. Do so whenever possible, between attacks.
  • Your structure building is essential for spiders to survive in the harsh cold environment of space. Make web passages for other spiders to pass through while simultaneously protecting the colonies atmos.
  • Your spikes can be used by ambush spiders, dragging intruders into them for extra damage.
Hunter Spider
  • You are fast, but not too fast. Don't go out hunting alone too far away from the nest.
  • Your prey will take some time to metabolize your venom - Stall them out until their body succumbs to it.
  • You are faster than the average spider. Use this to help slower folk by dragging more robust spiders into fights with you. Letting them tank the damage can let you live for another day.
  • Listen to the scouts - You will be the spiders into a battle. Work with scouts to find prey for the nest.
Scout spider.png

Scout Spider

  • You are the eyes of the nest. Run around, crawl around vents and inform the nest of any nearby intruders through Reports.
  • You deal low structural damage - Scouting out and opening paths to corpses or weak humans for other spiders to hunt will benefit the colony.
  • You are extremely fast. Use this to drag any injured spiders into a safe area, or into a battle area that requires combatants.
  • Not only are you extremely mobile, you can see all. Use your thermal vision to alert other spiders of nearby intruders to keep the nest a secret for a while longer, or to set up ambushes.
Guard Spider
  • Your damage is strong and your flesh is stronger. Protect other spiders from incoming attacks, and push humans away from the nest.
  • As you can tank plenty of damage, make sure to have a Nurse near you whenever possible.
Ambush spider.png

Ambush Spider

  • You are hard to detect, like a ghost. No one sees you coming through the webs - Use this to your advantage. Pull your enemies close and drag them into the webs to give yourself an advantage in combat.
  • You are extremely slow outside of webs. You should try to stick to the webs.
  • No, seriously, stay in the webs.
  • You are painfully slow outside of webs. If you absolutely need to leave them, try to get another spider faster than you to give you a helping leg, to pull enemies and lead them to their doom.
  • Try grappling into enemies during fights to temporarily stun them. A stunned spaceman is a dead spaceman in melee combat.


The most important thing for spiders is ensuring that there will be another generation for the spiders. If you're just starting out, getting your first kill is the most important part of ensuring the survival of your species as enriched eggs can grow into new broodmother spiders to produce eggs. If you came from xenobiology, follow your directives, damnit! They are your most important objective, more so than other spiders.

Fighting the spider infestation

Kill the Broodmothers

Remember, only Broodmother spiders can reproduce. If you kill all of them, you've already won. They are not hard to kill with 200 health it takes 8 lasers to kill them requiring a team effort they are usually in the center of the nest being protected by multiple spiders. They have extremely low damage so dealing with them alone shouldn't be to much trouble. Avoid other spiders if you can, as they're the ones who can wreck you.

Flood with space

Spiders still breathe, which makes getting a spacesuit and removing the station's air pretty viable. Now, obviously, this will incur the ire of your fellow spacemens, so it's more of a last resort. It does do a stellar job of killing spiders, though, as they can't put on a spacesuit. If you want to kill a lot of spiders without also turning your space station into a spaced station, although this strategy serves better per reserved spider areas since they can build web passages and other structures to block space floods.

Avoid webbing

Spider's webbing is their bread and butter. If they can't fight you, which hopefully is the case, the smart ones will recede back into their webbing and taunt you. Don't fall for it! Once you enter the webbing, the spider can destroy you, as you cannot move in some of the bigger webs.

Look at your surroundings

Spider nest tend to be full of unsuspected dangers watch out for web spikes as they can cause big damage without you even noticing them and be especially carful of Ambush spiders they are white and they can turn semi invisible that with their pull strength will send any careless spacemen into becoming spider food.

It's not safe to be alone

Spiders work best as a team and so do you against spiders make sure to bring a fellow comrade to help you deal against these arachnids .
