I've played half-a-dozen rounds as Engineer and still don't really understand how the TEG works.

Saw my first hellburn a second ago. Now I have even further questions.

Nobody knows. Nobody asks. It just does. Usually.

The funniest round I remember was when someone managed to kill a gravitational singularity by suplexing it to death with a wrestling belt.

Security charged him with murder and we held a trial. The star witness was... its son, a grieving sadularity. Unfortunately the trial had to be called off due to the sadularity absorbing most of the courtroom, causing the shuttle to be called.

Hellburn: if you mix exactly this ratio of plasma and oxygen, delete exactly these spots of flooring, fix exactly these broken pipes, and the RNG and/or Satan himself smiles upon you, the PTL suddenly has a use. (And you can cause people in Escape to spontaneously combust, which may be the actual feature of hellburning)

e. I've never hellburned myself, but I can get decent power out of char and inadvisable gas mixes in the hot loop. Two of plasma, one of oxygen, max pressure and kill the purge valve, and cackle madly seems to be my working recipe. But since I do it at the end of the round because power is failing and no one else has set up the engine, I have yet to discover if this will, in fact, burn down everything.

I can confirm that this will, in fact, burn down everything. It appears the superheated oxygen will expand, burst the pipes, and become as unto a dragon.

top tip for the TEG: you want the smallest possible volume of gas in the hot side and the largest in the cold side. dump every plasma can you can find on the station into the cold loop. plasma is the best conductor of heat energy by a wide margin.

the reason for this is the energy efficiency goes up the closer the pressures are, the volume of gas on the cold loop will drop in pressure when chilled, the hot loop will rise when heated.

i usually run the engine safe with just a tiny drop of plasma in the hot loop and all the rest of it in the cold loop but you can throw some oxygen in the hot loop and start a fire in the pipes if you're a madman. you can keep it running safe if you use the vents and the extra ports to fill empty cans to keep the pressure under control but without constant maintenance it will eventually explode.

you can also get fancy with a rare gas available through telescience that catalyzes co2 into oxygen in high temperature environments and get some really absurd results.

Oh just remembered a great round I had on Paradise (I know) a few months ago. Started as a normal Assistant with dreams of robustness, geared up with some hacking and engineering department neglect and started doing loops around the station exterior looking for trouble. Get to Xenobiology and it's just... Gone. Half the room is missing and the other half is on fire. Loot on my grubby little assistant mind I inspect some of the mangled bodies and find that one of them is actually still alive? Greed and do-goodery warred in my heart but in the end I dragged the unconscious scientist to medbay and they managed to fix her up. She gets up, thanks me, and tells me to follow her to telescience. Push a few buttons and she reappears holding an AI card. Turns out the AI was rogue the whole time and murdered her when she found out. Literally saved the station because I wanted space loot. In later rounds I actually ended up befriending her and would flash my ill gotten gains when I saw her at the bar (raiding the evidence room in a server full of try-hards and wannabe blue lives rocks). Best I ever got was a cryptographic sequencer. IMO being an assistant (especially on boring rounds/servers) is the most fun role.

It does for normal players, but it doesn't work at all for the AI.

There's a "Toggle Internal Radio" command under the "AI Commands" tab, but I haven't gotten it to work. Best I can do is turn the general radio on/off, or the machine radio on/off. Sometimes you want to let Security know where the Changeling is without letting the Changeling know. Or hound Engineering about putting out the fire in the engine room without bothering the rest of the station.

It works for a little while, but it lacks staying power. The oxygen catches fire in the pipes and converts to CO2, which can hold a lot less heat than plasma and therefore generally gums up the works.

Engine fundamentals:

In theory, you want a massive temperature difference between the two loops, with roughly equal pressure. The generator will transfer some heat from the hot loop to the cold loop, producing power in the process. In practice, heating gas will increase the pressure, while cooling gas will lower it, and it's a lot easier to heat gas than it is to cool gas. This means that it's difficult to keep the loops balanced. Also, if the gas pressure in a pipe exceeds 15000 or so, the pipes will burst, spewing their contents into the atmosphere at a rapid (but not instant) pace.

In terms of gases, plasma is most responsive to temperature change and therefore generally the optimal choice for both loops, but it's toxic to breathe and is notoriously flammable when in the presence of oxygen. Note that a pure-plasma atmosphere won't catch fire, as the presence of oxygen is mandatory for flames in SS13.

Also, note that gases can catch fire while still in pipes, generally with a massive spike in both heat and pressure, so exercise extreme caution when using plasma and oxygen together. As I mentioned above, fires convert oxygen to CO2, so you need some way of disposing of that CO2 if you want a plasma/oxygen mix to stay spicy. That's why plasma/oxygen combustion chamber burns usually involve an open chamber vent and often an RCDed tile or two - you want to get rid of the old gas that's been burning for a bit, since it'll pollute your chamber with useless CO2.

The basic principle behind hellburns is that although pipe leaks rapidly deplete the gas pressure in a pipe, the gas loss is slow enough that a really hot combustion chamber can actually make the gas pressure rise faster than the pipes can deplete it, meaning that the leaks don't have enough impact to actually impede engine function. Similarly, jacking up the heat enough can compensate for the efficiency losses from pressure differentials, insufficient cooling, and so on. So a hellburner throws all the guidelines from the beginning of this guide out the window, and instead focuses entirely on two things: making the combustion chamber as hot as possible, and minimizing the engineering department damage that'll inevitably result when the combustion chamber is burning hotter than a small star.

Though there is a third choice for traitors: figuring out someplace interesting to put that high-pressure superheated doom gas. Fun fact: did you know that on Cogmap1, one of the hot loop purge pipes passes beneath the sauna and heats it via a radiator in the floor before venting to space right near the bar?

A proper hellburn has gas so rapidly expanding from increasing heat that it literally can't leak out from the completely shattered pipes fast enough to depressurize.


Or on the absolutely magical occasion where you break thermodynamics entirely and rollover to below absolute zero, you flood the station with infinitely pressurized burning cold vacuum.

85% of people don't start the engine as it is, and the station runs out of power because of it. I'm not sure making it even harder to do so is a good idea.

Actually getting the engine going isn't too hard. Getting enough power to use the PTL is hurting my brain, though. Can you even generate enough power to use it without a hellburn?

I was a changeling on one of those magical rounds, it was great. They take no damage from cold or oxygen loss, so I just strolled around the station eating corpses off the floor and wondering why everyone else was suddenly keeling over.

This makes me wish I knew how the poo poo the BYOND code system worked, because making a hellburn even more magical sounds like fun. Get it hot enough for fusion beyond iron to start (about 3 billion kelvin) whereupon it starts leaking new and exciting things, like uranium, rubidium, and good old elemental plutonium. If you manage to really just break physics completely, you make it hot enough that the primordial hell-soup births another universe, which expands and dies, flagging you as a murderer.

It also needs to change the displayed name/title ingame once you do it.

My most recent setup is a pipe loop with 5 flusher inputs being fed by 10 thermal printers (that oddly contain infinite paper) with a sensor pipe triggering a cascade of flushes,
the sound of it was tremendous and dominating like the roar of a rocket engine,
