Competitive co op games put a team against the clock first and against other teams second, so they need a ladder of challenges that climb in clear steps. Bomb Appétit has 20 missions in four sections, from First bite, a single module with five minutes, to Double shift, fourteen modules and three needy ones in the bigger case.
Why do competitive co op games need a mission ladder?
A mission ladder lets a team measure itself before it measures itself against anyone else. Each step adds one kind of difficulty, such as more modules, a new module type, a needy module or fewer strikes, so a team can tell what beat it. A ladder also gives every leaderboard a fixed set of rules to compare times under.
In Bomb Appétit, a mission is a recipe for a bomb. It sets the time limit, how many regular modules appear and which types they are drawn from, how many needy modules join them, the size of the case, how many strikes the team may take and the rule seed of the manual. Every mission except the last uses rule seed 1, the standard manual. The missions page prints those settings on each card in a short line, for example "4 modules · 4:00 · 3 strikes · manual 1", together with the list of module types the bomb can draw from.
Because each mission fixes its own rules, each one also keeps its own leaderboard, and times are only ever compared with others on the same mission. The reasons for that design are in one board per mission. Our full post on how a defusal gets ranked on the leaderboards covers verified runs and percentiles.

Section 1 missions: First Bite to Quick Snack
Section 1, called Appetizers, teaches the first three module types one at a time. First bite is a single Wires module with five minutes on the clock. Button up adds the Big Button, and Strange symbols adds the Glyph Keypad. The last two missions keep those three types and cut the clock to four minutes.
First bite and Button up are the only missions that give every player exactly the same bomb. That makes them a gentle place to learn, since a group that replays First bite meets the same wires and can compare notes on what went wrong. The mission note for First bite sums up its purpose: learn to describe what you see. Button up asks the question the Big Button always asks, whether to tap it or hold it, and tells the Defuser to ask the Experts.
Strange symbols brings the first glyphs, and its note asks the team to agree on names for them. That advice matters for the rest of the game, because glyphs come back on most later bombs. Table for three then deals three random modules from the first three types with four minutes to solve them, so the team stops knowing in advance what it will face.
Quick snack closes the section with four modules in four minutes, and its note says simply to keep it moving. With four modules drawn from three types, at least one type turns up twice. It is the first mission where small delays add up to a lost bomb, which is why our post on getting faster without more strikes uses it for its worked timeline.
Section 2 missions: more modules, same case
Section 2, Main course, keeps the same 3x2 case and introduces three new module types: Color Echo, Word Grid and Recall. Its first three missions each give five minutes for three modules. Mixed plate then asks for five modules from the first six types in seven minutes, and Rush hour asks for six in six minutes.
Each opening mission in the section is built around one newcomer. Echo chamber leads with Color Echo, where pads flash and the Defuser answers, and its note warns that the mapping changes when you strike. Word salad leads with Word Grid and words that sound alike, and its advice is to spell them out. Second helpings leads with Recall, five stages in which the Defuser has to remember what was pressed, with no notes on the bomb.
Mixed plate is the first mission that can draw any of the six types introduced so far, and its seven minutes give room to meet them all. Rush hour removes that room. Six modules in six minutes is the first bomb where a team with more than one Expert benefits from dividing the work, and the mission note says so directly: split the manual between Experts.
The section's case size never changes, which is the point of its heading. The difficulty climbs only through the number and variety of modules, so a team can tell whether its trouble is with a module type or with keeping pace.
Section 3 missions: needy modules arrive
Section 3, House specials, adds three more regular module types and then the needy modules. Signal fire brings in the Blinker, and Spaghetti brings in Tangled Wires and Wire Panels. Pressure cooker is the first mission with a needy module, and by Back of house the team handles eight modules and two needy ones in nine minutes.
A needy module is one that can never be solved. It wakes up from time to time and needs quick attention until the rest of the bomb is done, and ignoring it for too long earns a strike. There are three. The Pressure Vent asks a yes or no question that must be answered before its timer ends. The Discharge Lever has a meter that fills and must be drained by holding the lever. The Dial Alignment changes its lights and wants the dial turned to match. How they interrupt a round is the subject of what needy modules do while the others are being solved, from our post on the three needy modules that never stay solved.
Pressure cooker introduces only the Pressure Vent, alongside four regular modules from the first six types, and its note warns that it will not wait for you. Full boil raises the count to six regular modules from nine types, with one needy module that may be the Discharge Lever. Its note mentions a lever that needs holding.
Back of house is the section's final test: eight regular modules, two needy ones drawn from all three needy types, and nine minutes. Its note tells the Defuser to check the back of the bomb, because with that many modules some of them will not be on the front.
Section 4 missions: The Works, Double Shift and the bigger case
Section 4, Chef's table, is the top of the ladder. Lost in the sauce introduces the last two module types, Labyrinth and Passcode. The works puts all eleven regular module types on one bomb. No substitutions cuts the strikes to two. Double shift moves to the bigger 4x3 case with fourteen modules and three needy ones.
Lost in the sauce is short for this section, four modules in six minutes, but it brings a maze that only the Experts can see and a passcode to spin. Once those are learned, the team has met every module in the game. The works then serves one of everything: eleven modules, one of each regular type, in eleven minutes with no needy modules.
No substitutions draws ten regular modules from the full set, adds one needy module and allows only two strikes in ten minutes. Its note counts the total as eleven modules, which is the ten regular ones plus the needy one. With two strikes, the second mistake ends the run, so the clock speeds up only once before there is no margin left.
Double shift is the largest bomb in the game. It is the only mission on the 4x3 case, and it asks for fourteen regular modules and three needy ones in fifteen minutes. The bigger case means more places for modules and for edgework to hide, and three needy modules mean someone is almost always being interrupted.
Double shift is not quite the last rung. The final mission is named Bomb Appétit, after the game: eleven modules, ten minutes and a single strike, on rule seed 2026. Its note calls it a manual nobody has seen before. Because the bomb and the manual must use the same seed, the Experts open the manual on seed 2026 instead of the standard seed 1, and rules memorised on seed 1 will not help.
Which mission should a team attempt next?
Move up when the current mission ends with time to spare on most attempts, and stay while defusals come down to the last few seconds. Inside a section, take missions in order. A new module type is a bigger step than a shorter clock, so expect the first mission of each section to feel harder than the one before it.
A few signals help a team choose:
- The clock at the end. If the team keeps finishing with a minute or more left, the mission has stopped teaching much. Move on.
- The strikes. If most runs end with two strikes on the case, the team is guessing. Stay, and work on describing and repeating back.
- The module that keeps causing trouble. If one type always slows the team down, a mission that leans on it, such as Echo chamber for Color Echo, is worth replaying before moving on.
- The size of the group. Missions such as Rush hour and Back of house reward several Experts who can divide the manual. A pair with one Expert may find the earlier missions in each section a better fit for longer.
Signed-in players can also use the leaderboard as a signal. Once a team has defused a mission, the missions page shows its best time left and, for ranked players, a percentile such as "Top 40%". A team sitting low on a board might replay that mission before climbing, while a team near the top has a reason to try the next one. Guests can play every mission in any order. Nothing is locked.
The mission mistake: skipping to Double Shift on night one
Opening a new group's first evening with Double shift usually ends the evening early. It asks for fourteen modules drawn from all eleven types, three needy modules and a bigger case to search, all in fifteen minutes. A team that has never read a Wires page spends that time learning the manual instead of defusing anything.
The trouble is not only the size. Double shift combines every difficulty the ladder introduces one at a time. The team has to agree on glyph names, spell out similar words, remember Recall stages, keep three different needy modules quiet and read edgework off a case with more room on it, all at once. Each of those is manageable after a mission that teaches it alone. Together, on a first night, they turn a party game into a long, quiet failure.
A better first night starts at the bottom. First bite teaches the group to describe a module, Button up adds a second type and Strange symbols adds the glyphs. Quick snack then shows the group what four minutes feel like. A group that enjoys that hour can come back for Section 2. Groups that want something different can build their own bomb in freeplay and practise there before a mission depends on it.
Double shift is worth saving. A team that has worked up through Back of house and The works will meet it with names agreed, a manual split and an edgework routine already in place.
