Construction

All this assumes you've figured out the game pretty well so far. You have, right?

If you're looking for the antiquated game mode where you constructed your own station, see Construction Game Mode.

Makin'

Weapons

Bombs

Butt bomb

Harmless prank. Works like a grenade.

You will need:

 A butt
 A timer

To build:

 Add the timer to the butt.

Suicide bomb vest

The payload will be triggered upon death of whoever is wearing the vest, heating the mixture inside the beaker by 30 K (see ignition temperatures) when so equipped. If required, the payload can be removed and the entire suit taken apart with a wrench.

You will need:

 A regular ballistic vest
 A health analyzer
 An igniter
 A grenade OR pipe bomb OR beaker
 A screwdriver
 A wrench (optional)

To build:

 Use a screwdriver on the igniter.
 Combine the igniter with the health analyzer.
 Secure the assembly with the screwdriver.
 Combine the assembly with the vest.
 If you intend to use the beaker, prepare a chemical mix of your choice.
 Attach the payload to the vest.

Rigged light tube/power cell

A rather uncommon and creative way to booby-trap machinery or whole rooms. It is not a bad idea to turn the power off before installing either of them.

You will need:

 A light tube OR power cell
 A syringe of plasma from a chemical dispenser

To build:

 Inject the light tube or power cell with plasma.

Pipe bomb

Not to be confused with the version traitors can order. Other materials can be used in place of welding fuel if available. Ordered by explosive power: phlogiston dust, phlogiston, CLF3, or black powder. Plasmastone and erebite work differently in that they are crafted from custom metal sheets, then combined with one of the listed reagents. A small variety of items can also be shoved into one or both of the pipe bomb's two pipes to add a special effect to the detonation. If you shove two of the same item inside a pipe bomb, the item's effect will be boosted.

You will need:

 3 metal sheets
 A cable coil
 An igniter
 A timer
 A container (beaker, glass etc.) of welding fuel (20 units)
 A welder
 A screwdriver
 Optionally, one or two additional items.

To build:

 Turn the metal sheets into a pipe frame. 
 Use the welder on the frame. 
 Optionally, stuff the extra item(s) in the hollow frame (note: you cannot do this once the frame is filled!). 
 Fill the frame with welding fuel.
 Add some wires.
 Use a screwdriver on the igniter.
 Combine the igniter with the timer.
 Add the timer/igniter assembly to the pipe frame.

Some possible extra items to add:

 Metal scrap
 Glass shards
 Butter
 Cloth
 Instruments
 Butt
 Glowstick
 Paper
 Ectoplasm
 Meat
 Telecrystal
 RCD cartridges
 Cable coils
 Power cells (only works in combination with aforementioned cable coils)
 Medical patch boxes
 Gold star boxes
 Assorted sticker boxes

And the great thing is, if the extra item isn't coded to have a special effect, it simply won't be added to the bomb. That is, if the item you're adding does go in, you know something special will happen!

Mousetrap bomb

Compatible with pipe bombs (regular, Syndicate) and grenades. They can be used as makeshift mines or to booby-trap backpacks and other containers. Can be taken apart with a wrench if required.

You will need:

 A mousetrap
 A pipe bomb OR grenade
 A wrench (optional)

To build:

 Attach the pipe bomb or grenade to the mousetrap.
 Don't forget to arm the mousetrap by clicking on it before use.

Mousetrap car

A mousetrap bomb on wheels. Once set in motion, the cart will scoot off in whichever direction you're facing and detonate the grenade upon impact with a large object or unfortunate bystander. Can be taken apart with a wrench if required.

You will need:

 3 metal sheets
 A mousetrap bomb (grenade or pipe bomb only)
 A wrench (optional)

To build:

 Turn the metal sheets into a pipe frame.
 Combine the mousetrap bomb with the pipe frame.

Igniter assembly pipe bomb

The venerable pipe bomb, but with a more complex primer. Unfortunately, it cannot be used with mousetraps. As with the standard pipe bomb, other materials can be used in place of welding fuel if available. Ordered by explosive power: phlogiston dust, phlogiston, CLF3, or black powder. Plasmastone and erebite work differently in that they are crafted from custom metal sheets, then combined with one of the listed reagents. A small variety of items can also be shoved into one or both of the pipe bomb's two pipes to add a special effect to the detonation. D You will need:

 3 metal sheets
 A cable coil
 An igniter
 A timer OR proximity sensor OR remote signaller
 A container (beaker, glass etc.) of welding fuel (20 units)
 A welder
 A screwdriver
 Optionally, one or two additional items.

To build:

 Turn the metal sheets into a pipe frame.
 Use the welder on the frame.
 Optionally, use the extra item(s) on the hollow frame (note: you cannot do this once the frame is filled!).
 Fill the frame with welding fuel.
 Add some wires.
 Use the screwdriver on the igniter.
 If you intend to employ a signaller, use the screwdriver on it as well.
 Combine the igniter with the timer, proximity sensor or signaller.
 Add the pipe frame to the igniter assembly.

Available additives:

 Butt
 Glowstick
 Paper
 Ectoplasm
 Meat
 ...And more!

Mousetrap pie launcher

For the seasoned prankster. Go on...open it! (Or just take it apart with a wrench.)

You will need:

 A mousetrap
 A left or right arm (any type)
 A pie (any type)
 A wrench (optional)

To build:

 Attach the arm to the mousetrap.
 Add the pie.
 Don't forget to arm the mousetrap by clicking on it before use.

Single tank bomb

Also known as plasma tank assemblies. Less powerful than transfer valve bombs, but they still fit in backpacks. You'll have to discover suitable gas mixtures yourself.

You will need:

 A plasma tank
 An igniter
 A timer OR proximity sensor OR remote signaller
 A screwdriver
 A welder

To build:

 Fill the plasma tank with a gas mixture of your choice.
 Use a screwdriver on the igniter.
 Combine the igniter with the timer, proximity sensor or remote signaller.
 Secure the assembly with the screwdriver.
 Attach the assembly to the plasma tank.
 Weld a hole in the tank.

Transfer valve bomb

Big bombs for a big bang. Again, this guide won't tell you how to create the perfect explosive mix, so feel free to sign up as a scientist and mess around with the equipment in the laboratory. You should also use the mainframe and VR goggles to run simulations instead of testing your bombs on the station.

You will need:

 A tank of heated gas (Tip: usually involves plasma.)
 A tank of a reactive gas (Tip: ...and oxygen.)
 A tank transfer valve
 A timer OR proximity sensor OR remote signaller

To build:

 Connect the first tank to the transfer valve.
 Do the same with the other tank.
 Attach the timer, proximity sensor or remote signaller to the transfer valve.

Transfer valve butt

To build this (mostly) harmless gimmick bomb, simply substitute the tank of reactive gas for a butt. No other modifications are necessary. Keep the pressure in the other tank high for a truly horrific blast.

Canister bomb

Massive bombs. As usual, the gas mixture is not revealed, only the assembly process.

BIG FUCKING WARNING NOTE: These bombs are no joke. The amount of hull they can take out of the station has the potential to warrant an Emergency Shuttle call, so if you're not an antagonist and seek to build a canister bomb for whatever reason, run it by the admins first with adminhelp, or detonate them somewhere away from it like the debris field, although you'll still want to inform people about it.

You will need:

 A canister full of an explosive gas mixture.
 A plasma tank filled to at least 700 kPa of pure plasma.
 A timer
 An igniter
 A cable coil
 A screwdriver
 A multitool
 A station bounced radio (optional) - Creates a command report upon priming.
 A remote signaller (optional)
 A crowbar (optional)
 A pair of wirecutters (optional)
 Suitable attachment class items (optional, see list below)

To build:

 Use the screwdriver to unsecure the igniter.
 Add the multitool to the igniter.
 Add the plasma tank to the assembly.
 Secure the assembly with a screwdriver.
 Use the cable coil on the assembly.
 Add the timer to the assembly.
 Optionally, add the station bounced radio to your assembly.
 Optionally, add a remote signalling device to your assembly.
 Optionally, add up to three attachment class items to your assembly.
 Use the assembly on the canister.

The detonator assembly may have up to 3 attachment class items. Each attachment adds an additional wire to the assembly, each having a unique effect. You may have more than one of any type of attachment.

 An analyzer (Detonates the bomb if the gas is leaking from the canister.)
 A power cell (Adds an additional detonation wire.)
 A flash (Occasionally flashes nearby people.)
 A sheet of paper and a pen (Adds a note to the canister bomb interface.)
 A bike horn (Self-explanatory.)
 A vuvuzela. (Ditto.)

Detonators may be disassembled if necessary. A screwdriver is required to unscrew and a crowbar is required to pry out the plasma tank, and everything else can be cut apart with the wirecutters. Attachments may be removed from the assembly with a screwdriver.

Stun gloves

Insulated gloves armed with a powerful shock to briefly stun whomever they touch. Your intent must be set to harm in order for this to work. Craftable stun gloves only hold one charge at a time.

You will need:

 A pair of insulated gloves OR power gloves
 A charged power cell
 A cable coil

To build:

 Add some wiring to the gloves.

Zip gun

You can use different types of ammunition, of which .38 Special is easiest to obtain from a hacked general manufacturer. The zip gun holds two rounds at a time.

You will need:

 3 metal sheets
 A welder
 A staple gun

To build:

 Turn the metal sheets into a pipe frame.
 Use the welder on the frame.
 Combine the staple gun with the frame.

Flash/cell assembly

In addition to stunning people like any other flash, this overcharged version also sets them on fire. Unlike a regular flash, it will only work once. If required, the assembly can be taken apart by using a screwdriver followed by a wrench.

You will need:

 A flash
 A charged power cell
 A screwdriver
 A wrench (optional)

To build:

 Open the flash's battery compartment with the screwdriver.
 Attach the power cell to the flash.

Poisoned surgery tools

Certain surgery tools can be dipped in a poison or other reagent for fun and wacky effects upon stabbing.

You will need:

 A scalpel OR saw OR enucleation spoon
 A filled container (beaker, glass etc.)

To build:

 Dip the scalpel, saw or spoon in the beaker.

Poisoned arrows

Likewise, arrows from the nano-fab can be dipped in a container of poison or other reagents, applying their effects upon hit.

You will need:

 An arrow, obviously.
 A filled container (beaker, glass etc.)

To build:

 Dip the arrow into the container.

Broken bottle

A passable melee weapon that makes a decent, better-than-average throwing weapon.

You will need:

 A bottle, obviously.
 A table to break the bottle upon.

To build:

 Make sure you're on Harm intent.
 Use the bottle on the table.

It might take a few attempts/bottles. By default, there's a 25% chance you'll successfully break the bottle; if you're drunk and/or if you're the Barman, you're more likely to succeed. If you fail, reality will ensue, and the bottle will smash into a slightly less useful glass shard. If you're especially unlucky, the broken glass may cut your hand and make you bleed.

Miscellaneous assemblies

Timers and other basic tools may be put together as assemblies, most of which can function as bomb detonators. Not included is the health analyzer/igniter combination, a suicide bomb vest-specific trigger.

 Regular floors can be made in space by:
   - using rods first on empty space, creating a lattice
   - then placing a floor tile on top of it (floor tiles can be made from a sheet of metal)
 Use another floor tile on the plating to create a regular floor.
 Fire-resistant floors can be made using one floor tile, and one rods
 Use rods on plating to create a floor similar to the engine floor

Barricades

 Barricades can be made in space by:
   - using rods first on empty space, creating a lattice
   - then using more rods on the lattice to create the barricade
   - and can be reinforced with even more rods

Hidden Doors

Entire Rooms

ABC-Us and blueprint markers can be found in the Cold Loop on Cogmap2 and the Warehouse areas of other maps. You don't need to replicate entire rooms. You can pick a section of it or multiple sections to create different rooms. The blueprint marker can create multiple blueprints before running out of energy. This way you can pick all the pieces you want in advance and put them together in a new configuration. Remember to save them with their own names so you don't get them mixed.

You will need:

ABC-U (Automated Blueprint Construction Unit)
Blueprint marker
Metal and glass sheets (usually a few hundred!)

To build:

Select tiles using blueprint marker.
Print a blueprint from the marker and put it in the ABC-U. (If you can no longer print the blueprint from that specific blueprint marker, save the blueprint. You will then be able to print it from other markers.)
Check the material cost on the ABC-U and load accordingly.
Drag the ABC-U in position, lock it down and make it start building.

Note: ABC-Us can only make new rooms on space tiles, so having EVA equipment is a must.

Misc

Building and fixing disposal pipes

Like most things in Space Station 13, the plumbing system is surprisingly deep. A skilled space plumber can set you up for a wild ride that'll send you racing through most of the station and spit you out from a mailbox. Now you can be that skilled plumber.

The building blocks

There's a few pipe dispensers scattered around the station. The most easily accessible one can be found in disposals. Pipes come in 8 variations, 5 of which the dispensers will provide:

Straight - Straight tube.
Bent - Tube bent at a 90 degree angle.
Junction - A three-way junction. The arrow indicates where items exit.
Y-junction - A three-way junction with another exit point.
Trunk - Entry and exit point for pipes. Disposal and mail chutes come pre-connected to these, but players can't connect on their own.
Mail-junction - Not available from the dispenser. A three-way junction with a filter that only allows items to pass through. People and creatures will be diverted away into the side-pipe. Visually distinguished from regular junctions by a red dot on the pipe.
Controlled pipe segments - Specialized equipment available to mechanics.

Managing your pipes

Pipes come in four states:

Free - Can be moved, rotated and flipped over by right-clicking on them.
Wrenched - Wrenched to the floor. Immobile and inoperable. You can walk over them and rotate them.
Welded - Welded to the floor. Immobile and can't be rotated. Fully operable.
Broken - Welded to the floor. Inoperable. Must be welded at all ends to remove.

You need three tools. A crowbar to remove the tiles covering the floor. This exposes existing pipes and lets you place new pipes. A wrench to fasten free pipes. A welding tool to make wrenched pipes operable or to loosen welded pipes.

Controlling the flow

Take these tips to heart and you'll be a plumbing like a champion in no time.

• T-ray scanners show you pipes hidden under floor tiles.
• Always wrench the pipe in place before welding it. Poorly secured pipes will break the floor tile covering it and fall out of place.
• Items will follow the pipeline from chute to exit point as long as every piece is connected, nothing is broken and there's no blockage.
• Items entering a junction from the wrong end (the side with the exit arrow), will randomly go out one of the two other sides.
• Fat people are poorly suited for pipes and can easily create a blockage. Blockages can be cleared by unwelding the blocked section.
• Pipelines ending in a regular pipe will shoot things out in a straight line. Trunks eject items in random directions.
• Combine with programmable electronics components to make some truly wild rides.

Table

 Screwdriver the door to close it up when finished.
 Crowbar also opens powered doors, whose test lights are off,and
 the bolts up.

Door wiring is randomized per game, but all doors have the same wires. Using a multitool to pulse wires will only work if the door has power. Cutting wires can rid the door of some features (AI Control for instance) until the said wire is mended.

APC

 Screwdriver
 Click on APC and drag the windows away from each other so you can see both at once
 Get wirecutters out of your toolbox/backpack/pockets and use them on the APC with the windows still open

There are four wires. Two short out the APC when cut, one cuts AI control when cut, and one does nothing when cut, but unlocks the APC when pulsed with a multitool. There's a chance you'll get shocked when cutting wires, so either have insulated gloves or do it in an isolated area where no-one will find you. South maintenance is a good choice.
