Playing Detroit: Become Human is less about mastery and more about managing consequence.
I spent about 40 hours on my first run, then another 30 across multiple playthroughs to see how the branching actually functions. The game tracks hundreds of tiny decisions and compiles them into a few major story paths. Most people treat it like an interactive movie and just keep pressing forward. That works, but you miss nearly everything worth knowing. Before I explain the guide structure, let me get ahead of a problem that tripped me up for hours. The game saves automatically at key moments, but it also has manual save slots. I learned the hard way that if you only use the automatic saves, you will lose the ability to backtrack to small conversation choices. You need to create manual saves before every chapter transition and after major decision points. I kept forgetting this and would accidentally advance a storyline I wanted to keep open for later exploration. That costs you roughly 15 to 20 minutes of replay time per mistake. The guide itself is not one single document. It is a collection of flowcharts, ending breakdowns, and achievement lists. The most useful version tracks which choices unlock which endings. There are three main characters, each with their own path, and several endings total. I found that focusing on one character per run is the most efficient way to map the story. Trying to explore all three routes simultaneously in a single playthrough just fragments your attention and makes the branching feel more chaotic than it actually is.
How the choice system works under the hood
Detroit: Become Human uses a hidden approval system tied to the protagonists. Connor has a deviancy meter, Kara has a family bond meter, and Markus has a violence meter. These numbers determine which endings become available and which characters survive. The game does not tell you these numbers exist. You have to infer them from dialogue cues and character reactions. This is the most counter-intuitive part of the whole experience. Most players assume the story branches only on obvious dialogue selections, but the hidden meters are what actually gate certain scenes and outcomes. Connor's deviancy meter fills when you choose empathetic or rebellious options during investigations and confrontations. If it gets too high, certain story beats change entirely. If it stays low, you get a completely different set of available actions. The mid-point sequence where Connor interrogates Chloe is where this becomes painfully obvious. I got locked out of a major choice because I had been too aggressive in earlier sections and never noticed the shift in how NPCs responded to me.
Running the walkthrough in practice
When you use a guide during play, the trick is knowing when to consult it and when to play without looking. I recommend playing the first chapter completely blind. Then after that opening section, switch to a chapter-by-chapter guide. The early game rewards intuition because it establishes your base stats and relationship parameters. Later chapters are where the branching intensifies and the guide becomes necessary. The flowcharts on most sites look overwhelming at first glance. They are accurate but dense. I found it helpful to print or screenshot the branch point I was currently at rather than scrolling through the entire document. You do not need context from six hours ago when you are making a decision in real time. Just look at the immediate choice tree and plan your next two or three moves ahead.

Achievements and completion requirements
There are 19 achievements in total. Several of them require a specific ending, which means you cannot earn all of them in a single run. The achievement list itself acts as a secondary guide because it tells you exactly which endings you need to reach. I ran two complete playthroughs to hit 100 percent. The second run took about 6 hours because I already knew the structure and only needed to diverge at key branches. One common trap: the "Happy Family" achievement locks you into Kara's storyline and will not let you return to Connor's path afterward. If you care about seeing everything, do not rush toward that ending in your first playthrough. It is easy to miss because the game makes Kara's arc feel emotionally urgent and pushes you toward it naturally.
Where to find the guide and related resources
The most reliable Detroit Become Human Guide materials are on community wiki pages and dedicated walkthrough sites. I rely on a combination of the official game manuals embedded in each chapter and third-party flowcharts for the endings I have not yet unlocked. The game itself includes a best wishes tracker that logs major decisions. It is incomplete, but it is better than nothing when you want to verify a past choice without reloading an old save. There is no single downloadable PDF that covers everything comprehensively. The guide exists as scattered web content, which is why building your own reference sheet during playthroughs is worth the effort. I kept a simple text file with chapter number, decision made, and resulting path tag. After three runs, that file became more useful than any published guide because it reflected my personal progression and the specific choices I had already confirmed worked.
What the guide cannot do for you
Even with a perfect walkthrough, there are sections where the game forces sequences you cannot alter. The QTE-heavy confrontation scenes and certain linear chase segments have no branching options at all. A guide will tell you this explicitly, but you will only notice when you try to deviate and find that you cannot. These moments are roughly 10 to 15 minutes per occurrence, spread across the three acts. Plan your playtime accordingly if you are trying to optimize for completion percentage. The other limitation is that some endings have very narrow conditions. I tried reaching a particular conclusion by making what seemed like the right narrative choices, only to discover that a minor dialogue option three chapters earlier was the actual trigger. The guide flagged it eventually, but not before I had wasted another hour. This is why keeping manual saves is not optional if you want a usable Detroit Become Human Guide to function properly.
