Needy modules are the three panels in Bomb Appétit that can never be solved: Pressure Vent, Discharge Lever and Dial Alignment. Each wakes 20 to 45 seconds after the bomb starts and keeps demanding attention until the bomb is defused. Ignore one and it costs a strike, so someone must keep watching them.
What needy modules do while the others are being solved
A needy module sits on the case beside the regular ones but never counts toward the defusal. It wakes on its own timer, asks for something within a short window, then goes quiet again. Get it right and nothing happens. Get it wrong, or let the window run out, and the bomb takes a strike.
The bomb treats needy modules differently in a few visible ways. Each has a yellow status light instead of the usual one. While a Pressure Vent or Dial Alignment is asleep, its panel dims and shows "Z z z". The "Solved" counter at the top of the screen counts only regular modules, so a bomb with eight regular modules and two needy ones reads out of eight. When every regular module is solved, the bomb is defused, whatever the needy modules are doing.
Experts in an online room never see the bomb, but they are told when a needy module wakes. Their status bar shows a "Needy module awake" badge next to the timer and strikes, and a sound plays at the same moment for both the Defuser and the Experts.
Here are the three needy modules side by side, using the game's own numbers.
| Needy module | What wakes it | What the Defuser does | Time to act | Rest between activations |
|---|---|---|---|---|
| Pressure Vent | Its own timer, first 20 to 45 seconds after the bomb starts | Reads the question aloud, then presses Yes or No | A 40 second countdown | Sleeps 15 to 30 seconds after each answer or timeout |
| Discharge Lever | Starts filling 20 to 45 seconds after the bomb starts | Holds the lever to drain the meter, lets go when it is empty | The meter fills from empty in 45 seconds | Never sleeps: once running, the meter keeps filling |
| Dial Alignment | Its own timer, first 20 to 45 seconds after the bomb starts | Reads out twelve lights, turns the dial to the matching direction | A 40 second countdown, judged at zero | Sleeps 15 to 30 seconds after each check |
The first needy module appears in the mission Pressure cooker, and later missions add more until Double shift carries three at once. The missions guide covers that ramp in the section 3 missions where needy modules arrive, and the full ladder of twenty missions is in the guide to competitive co op missions from First Bite up.
What does Pressure Vent want, and how fast?
Pressure Vent wants a yes or a no to a printed question, within 40 seconds. When it wakes, its vent opens, a question appears and a countdown starts. The Defuser reads the question aloud word for word. The Expert finds it in the manual's table and says the answer next to it. The Defuser presses Yes or No.
The questions are short kitchen nonsense, such as "Whisk the wick?" or "Is the lid rattling?". They are meant to sound plausible either way, which is why nobody should answer from instinct. Each manual lists six questions with an answer beside each, and the game makes sure every manual has at least two yes answers and two no answers, so pressing the same button every time fails.
Three outcomes are possible each time it wakes.
- The Defuser presses the answer the manual gives. The vent closes and the module sleeps for 15 to 30 seconds.
- The Defuser presses the other button. That is a strike, and the module still goes back to sleep.
- Nobody presses anything before the countdown reaches zero. That is also a strike, and it sleeps.
The countdown turns red and pulses for its last ten seconds, a useful cue for a Defuser who has been heads-down on another module. Forty seconds is long enough to finish a sentence on another panel before switching, but not long enough to finish a whole module. Answer it as soon as it wakes, then go back.
The table on the Pressure Vent page is small, so an Expert who owns it can learn its six lines during the first quiet stretch of a round. Read the question back once before answering. Two questions can share words, and a confident answer to the wrong one costs the same strike as a guess.
Discharge Lever: holding before the meter fills
Discharge Lever is the needy module the Experts cannot help with. Its manual page says it needs no expert help. A meter fills on its own, a full meter is a strike, and the Defuser holds the lever down to drain it, letting go once it is empty. The whole job is noticing it in time.
The panel shows a tall meter, a percentage readout and a large red lever labelled "Hold". Before it starts, the readout shows two dashes and the panel shows "Z z z". Once running, the meter climbs from empty to full in 45 seconds if nobody touches it. A dashed line crosses the meter at 60 percent. Above that line the fill and the readout turn red, and the label above the lever changes from "Charging" to "Pull now!".
Holding the lever drains the meter five times as fast as it fills, so a full meter empties in about nine seconds. The label reads "Draining" while it is held. Release once the meter shows zero; holding longer gains nothing.
Unlike the other two needy modules, Discharge Lever never sleeps. If the meter does reach full, the bomb takes a strike and the meter starts again from empty, filling at once. It keeps cycling until the bomb is defused or goes off.
Because it needs no lookup, the risk is pure attention. A Defuser deep in a Labyrinth can forget the meter entirely. A good habit is a glance at the lever every time a module is solved, and a quick hold whenever the meter is past the dashed line. With a single mouse or one finger on a touch screen, holding the lever also means not touching anything else for those seconds, so finish the current press first.
Dial Alignment: turning to match the lights
Dial Alignment wants its dial pointing the right way when its countdown reaches zero. When it wakes, it shows twelve lights in two rows of six and a 40 second countdown. The Defuser reads both rows, left to right. The Expert finds the matching picture in the manual, which gives a direction: up, right, down or left.
The dial has one button, and each press turns it one step clockwise: up to right, right to down, down to left, left to up. So reaching any direction takes at most three presses. The module checks only at zero. Turning the dial halfway through the countdown is fine, and so is turning it with five seconds left, as long as it points the right way when the window closes.
The manual page prints its patterns as rows of circles, filled for a lit light and hollow for a dark one. There are eight patterns, and every direction appears twice, so no direction is a safe guess. No two patterns are the same.
A read-out works best as a plain list. Here is an example; the pattern is only an example and the answer will depend on the manual.
- Defuser: "Dial is awake. Top row: on, off, off, on, on, off. Bottom row: off, on, off, off, on, on. Dial points left."
- Expert: finds the picture with those two rows and reads its direction aloud.
- Defuser: says the direction back, then presses the turn button until the dial points there.
Two details catch teams out. The dial stays where it was left between activations, so the Defuser should say where it points now, not where it pointed last time. And if the dial points the wrong way at zero, that is a strike, after which the module sleeps and wakes later with new lights.
Who should watch the needy modules?
One named person should own them. In a same-room game that is usually the Defuser, who sees every panel and the status lights. With two or more Experts, a second person should also own the needy pages of the manual, so the lookup is ready the moment the Defuser calls one out.
The Defuser's part is noticing. A quick sweep of the case after every solved module catches a Pressure Vent or Dial Alignment that has just woken, and a glance at the Discharge Lever meter keeps it below the dashed line. In an online room, the Experts' "Needy module awake" badge and its sound give everyone a second chance to notice.
The Expert's part is being ready. The Pressure Vent table and the Dial Alignment pictures are both short, and the Expert who owns them can study them during quiet stretches. That Expert should keep the manual open on those pages, or know exactly where they are. The guide to how the manual's pages are organized shows the order of the sections and the keyboard shortcuts that jump between them.
With three or more players, splitting the manual so one Expert holds the needy pages is the cleanest arrangement. The post on games for three players goes into splitting the manual between two Experts, including who takes which pages.
A two-player team has no spare Expert, so the single Expert holds everything. In that case, agree on a phrase the Defuser uses to interrupt, such as "needy", and have the Expert drop whatever they are reading and switch pages straight away. Then return to the module that was interrupted.
The needy mistake: everyone solving and nobody watching
The usual way needy modules hurt a team is quiet neglect. Everyone is focused on a hard regular module, nobody looks at the countdown on the Pressure Vent, and the first sign of trouble is the strike. Each strike also speeds up the bomb's countdown, so one ignored question makes every remaining module more rushed.
The timing makes this easy to fall into. No needy module can wake in the first 20 seconds after the bomb starts, which feels like a safe stretch, and it is. Spend it on the edgework read-out. The serial number, batteries, indicators and ports are needed by several regular modules, and reading them early is covered in the guide to reading the edgework aloud. By the time a needy module can wake, that note is already written.
After that, the danger comes from long modules. Labyrinth, Wire Panels and Passcode all keep the Defuser and an Expert locked together for many exchanges. A Pressure Vent that wakes in the middle of a maze is easy to miss. Agree before the round that the Defuser pauses a long module, answers the needy one, and then resumes.
Missions with a tight strike limit make this worse. The mission No substitutions allows only two strikes and carries a needy module, so a single forgotten Pressure Vent uses up half the margin. On Double shift, with three needy modules and fourteen regular ones on a bigger case, someone has to be looking at the needy panels all the time.
A last habit helps more than any other: say it out loud. When the Defuser sees a needy module wake, they name it, even if they can handle it alone. "Lever at seventy" or "vent awake" costs a second and tells every Expert why the Defuser has stopped talking about wires. Try it on the missions page starting with Pressure cooker.
