Backpack Boy: All Achievements Guide
Backpack Boy hides 19 achievements behind its time-looping puzzle platforming, and a single careful save file can collect 17 of them in one evening. Heavy spoilers follow, including how the game actually ends, so come back after your first playthrough if you want to go in blind.
One thing to understand before chasing anything: finishing the story is not finishing the game. The finale you reach on a first playthrough rolls no credits, and if you have the run timer turned on you will see it keep counting. That is a strong hint that something is still open. The real conclusion is unlocked separately, and several achievements live on that second route.
Story achievements
Nine achievements arrive on their own while you play. There is nothing to hunt down and no way to miss them, with one exception. The menu has a level-skip option, and using it voids the natural unlocks along with the completion reward at the bottom of this page. Leave it alone on your first save.
In order: A Flashlight?, Escaped!, Safe Inside, A Remote?, Poison Released, Input Accepted, Free From The Lab, The Tower, and The End…, which closes the first loop.
When The End… pops, note what does not happen: no credits, and the timer keeps running. That is the game telling you this was the false stopping point.
Secret achievements
Three unlocks are missable, all tucked into optional corners of the main route.
A Tape Machine?
In the room with the stacked crates, climb to the top of the stack and slip out through the gap in the upper right instead of taking the obvious exit. That drops you into an alternate part of the next area; climb up from there and you reach the tape machine. To activate the machine, pick it up the same way you carry crates. Walking up to it is not enough.
Find The Loopback Room
The Loopback Room starts you in the future half of the level. Step through the portal into the past, then commit to one direction: keep moving left, past the point where it feels like the level should have ended, and you eventually come out in the second tape room. The unlock triggers on arrival.
The View From Halfway Down
At the tree puzzle, ignore the objective for a moment and head left of the tree. Walk right up to the cliff edge and pause there. Taking in the view from halfway down is the whole trick, and the achievement fires on the spot.
The true ending
Back at the entrance area sits an elevator with a keypad. Enter the secret code there, Yellow, Green, Blue, Red, Yellow, the same five-button sequence the story showed you, and the true route opens. You can do this immediately after the story finale, or right at the start of any save.
A 2nd Chance pops the moment the true route begins.
Poison Released Again arrives partway through the second route. It is the same gas from the story, set off a second time, and this time it plays out differently. There is nothing extra to do here; it unlocks as the sequence plays out around you.
The End marks the genuine finale: the timer stops, and the credits finally roll.
100% asks for the full journey on one file: story and true route on the same save, from start to finish, with zero skips used anywhere.
Aren’t You Forgetting Something rewards doing things backwards: reach the true route without having looped at all. Easiest done on a fresh save: walk straight to the elevator, punch in the code, and skip the story entirely.
Challenge achievements
Two unlocks ask you to replay the whole thing, story and true route both, under a condition.
Speedrunner wants the complete run in under an hour. The limit is generous: knowing the puzzle solutions matters far more than movement tech, and a run with a handful of deaths and a forgotten room still fits inside the hour comfortably.
Deathless wants the complete run with zero deaths. Restarting a room does not count as dying, which softens it considerably, so restart early whenever a section starts going wrong. As of the launch build there is also a quirk worth knowing: unlike 100%, these two challenge unlocks are not voided by level-skipping, and only the three mandatory boss fights have to be played out: the first one, the outdoor one, and the finale. Expect that to be patched eventually; the intended route is the honest one.
