A guide to all six games in The Henry Stickmin Collection: how the choose-your-path format works, how branches carry between episodes, how to clean up every fail, bio, rank, and ending, and how to approach the 82 Steam achievements without spoiling every joke.
Researched September 2026 — current as of the Steam release (August 7, 2020, PuffballsUnited / published by Innersloth). The collection has had no major content updates since. Live games change; check the linked sources if something differs.
| # | Game | Structure | Unique fails (per achievements) |
|---|---|---|---|
| 1 | Breaking the Bank | Short and linear, fully reanimated for the collection | 5 ("Pentafail") |
| 2 | Escaping the Prison | Linear with several choice points | 18 ("Prisoneer") |
| 3 | Stealing the Diamond | Linear, longer | 40 ("Failsterpiece") |
| 4 | Infiltrating the Airship | Branching, multiple endings | 60 ("Frequent Failer") |
| 5 | Fleeing the Complex | Branching, multiple endings | 60 ("Notorious Failster") |
| 6 | Completing the Mission | New for the collection, about three times larger than any earlier game, many endings | 164 ("The Story Ends") |
Escaping the Prison, Stealing the Diamond, Infiltrating the Airship, and Fleeing the Complex were remastered with redone backgrounds and sound effects. Completing the Mission is the brand-new finale that caps off the series.
| Character | Role |
|---|---|
| Henry Stickmin | The silent protagonist; thief, prisoner, and eventually a lot more depending on your choices |
| Charles Calvin | Enthusiastic government helicopter pilot and Henry's most frequent ally ("calling in your buddy Charles") |
| Ellie Rose | A fellow inmate who can become Henry's partner in Fleeing the Complex |
| The Toppat Clan | A top-hat-wearing criminal organization that Henry keeps running into from the Airship onward |
| Reginald Copperbottom | Leader of the Toppat Clan |
| Right Hand Man | Reginald's second-in-command, a recurring rival |
| General Galeforce | The government commander who recruits or opposes Henry depending on the path |
Your relationship with the government and the Toppat Clan is the main axis of the branching: several paths put Henry on the government's side, others put him inside the Clan, and some leave him working solo. That's the easiest way to keep track of which endings you haven't seen yet.
From Infiltrating the Airship onward, the story splits. Finishing a path gives a rank (shown on Steam as abbreviations like "Rank: GSPI" or "Rank: CA"). Fleeing the Complex's ranks include:
| Rank | Meaning |
|---|---|
| CA | Convict Allies |
| PD | Presumed Dead |
| GI | Ghost Inmate |
| TB | The Betrayed |
| IRO | International Rescue Operative |
The Steam list has 15 rank achievements in total. Besides the five above, they are SE, LU, BBO, IoaS, JPE, UB, GSPI, PBT, RPE, and RBH, earned on the ending screens of the earlier branching games (Infiltrating the Airship's government-side ending, for example, is GSPI). The game spells out each rank's full name when you earn it, so use that screen to tick them off.
Strategy: play each branch through once for the story, then go back specifically for fails. Trying to collect every fail on your first pass through a branch slows the pacing and spoils the fun of the next reveal.
| Goal | Games | Achievement(s) |
|---|---|---|
| Complete Breaking the Bank | 1 | "The Story Begins" |
| All unique fails | All six | Pentafail, Prisoneer, Failsterpiece, Frequent Failer, Notorious Failster, The Story Ends |
| All bios | 1 to 6 | Bank Account, Prisoner Log, The Ledger, Membership, Roll Call, Allies & Enemies |
| All ranks | Airship and Complex | 15 "Rank:" achievements |
| All endings | Completing the Mission | 16 "Ending:" achievements |
The Steam list has many hidden or joke achievements with only hints. Some of the hints, verbatim:
More hints from the Steam list, for the harder-to-guess ones:
| Achievement | Hint on Steam |
|---|---|
| Bound to the Earth | "Oh my goodNess!" |
| xXn00bslayerXx | "LOUD SOUNDS" |
| 100111010 | A line of hex code (decode it for the clue) |
| Play of the Game | "THIS is Play of the Game..?" |
| Gold | "Is it edible?" |
| It's a joke... | "I'm not dumb, ok?" |
| Donut Want | "...or do you?" |
| This is fun! | "Hee Hee Hee haha!" |
| Buttery Snack | "yum yum" |
| Famous Movie Line | "Okay, it's not THAT famous." |
| Greasy Delight | "Rub some butter on that bad boy." |
| brUGHNO | "Gettin' real sick of seeing this guy." |
| Nailed it! | "Stuck the landing." |
| lolbrawlreference | "lmao" |
| You Win! | "Good job!" |
A handful more (Spooked, LOLOLOL!!11, tl; dr, BRAAAGH!!, Easy Achievement, braaagghh.., Respects, aeiou, BEEEEEEEE, Multiverse Correction, BRRYYESS!) have no hint at all. Most of these are gag fails or reactions, so the "try every option" rule covers them.
These come from clicking hidden objects, choosing specific fail options, or seeing particular scenes. If you want to find them yourself, the general rule is: click on anything that looks interactive, try every option in every scene, and pay attention to jokes that call back to earlier games.
Very short. See all five fails ("Pentafail") in one sitting.
Every choice screen has a few options; most are fails. Clear the list methodically — pick options left to right at each screen.
Longer, with more choice screens. It's the first game where it pays to keep a mental note of which option you haven't tried at each screen.
The first fully branching game. Paths split early, and your choices (who you side with) define both the rank you get and how later games continue. Finish one path, then go back and take the other options.
Also branching, with five ranks. Some paths involve teaming up with other characters. The rank names above tell you roughly which direction each path goes.
The largest game by far, with 164 unique fails and 16 endings. Expect several hours for a full cleanup. The menus make it easy to see which ending you still need.
How long is The Henry Stickmin Collection? The main paths through all six games take a few hours; 100% (every fail, bio, rank, and ending) takes considerably longer, mostly in Completing the Mission.
Is Completing the Mission only in the collection? Yes. It was brand new with the collection, "never before seen online."
Do I need to play the Flash originals? No. The collection includes all five earlier games, remastered, plus the finale.
Who made it? PuffballsUnited (Marcus Bromander and team), published by Innersloth, the studio behind Among Us.
Which ending is canon? The game presents multiple endings as "entirely canon." Pick your favorite.
How many achievements are there? 82 on Steam, including all ranks, endings, fail and bio collections, and many hidden joke achievements.
What's the hardest achievement? "The Story Ends" (all 164 unique fails in Completing the Mission) takes the longest.
