Eleven minutes of Dead Cells with the Broker commentating live, recorded by the developer on a Founder Alpha build. A fast roguelike is a hard game to narrate; watch how he keeps up, and where he does not.
A real session: the developer playing Dead Cells on a Windows PC with Signal Broker running, the Broker watching the game window and commentating in his own voice. Nothing is scripted and nothing was re-recorded; what he says is what the build produced at the time, including the lines that miss.
A bit of Dead Cells commentary from the Broker. He’s really gaining up on the commentary quality, not missing any detail. Though it would be hard to narrate this game, he’s done it flawlessly. To bad I didn’t press record immediately so some of his original commentary is in the void now.
He is a character, not an assistant: you do not type to him and he does not wait to be asked. Silence is a decision he makes; the Broker Bar in the app shows LISTENING in that case. The same character ships in Founder Alpha today, with the current build’s capabilities and limits.
Moments from this recording
Read from the recording itself: the Broker’s words are what his overlay showed at that moment, the time is where the audio-derived captions place them, and “what the frame shows” is the game picture at that second. Hits and misses both count; nobody listened to the audio to write this.
0:03He reads the loadout
accurate The three items he names are the ones on the screen; the slip is the “empty” collar slot, which holds Prisoner’s Collar I.
Dead Cells recording at 0:03.
Solid start with the rusty sword as main hitter. Firebrands sounds handy for burning enemies while Wolf Trap’s crowd control looks like a good setup for tougher fights. Could use a better shield or mobility tool soon. The collar slot empty, huh? Curious if you found anything to fill it yet.
What the frame shows. The pause menu’s Equipment screen: Rusty Sword I (138 DPS), Firebrands I (“Burns enemies and the ground”), Wolf Trap I, and a fourth slot holding Prisoner’s Collar I.
accurate The full bar is what he leads with; the “glowing shard” is most likely the weapon pickup, which he does not name.
Dead Cells recording at 2:02.
Full health, bright as hell, and that glowing shard’s tempting. Still feels quiet, but purple spikes or liquid ahead might sting bad if I rush it. Time to see what’s behind that locked door or if there’s a safer route. Need to keep my eyes peeled for traps or hidden paths. Not get cocky now.
What the frame shows. The health bar is full, about half a minute after he put it at “barely over a third”; the player stands by an Electric Whip II pickup with its item card open.
late The stall and the gold belong to his previous line about the shop (3:05–3:27); the key pickup on screen goes unmentioned.
Dead Cells recording at 3:35.
Fresh face at the stall, huh? Merch’s playin’ it cool but you know they’re sizing me up. Gold’s light in my pockets today, but that glow ain’t fading. Let’s see what tricks this place hides next. No rush, but I’m not here to be a ghost either.
What the frame shows. A blue corridor where the player picks up a key: the game’s own text says “Meh, just some rusty old key”, and at 3:44 the notice reads Dilapidated Arboretum Key.
inaccurate He treats a friendly character as a threat, and by the time the line appears the game has moved on to a menu.
Dead Cells recording at 5:37.
Alright, this big guy looks like trouble. I’m barely holding on with that health, gotta keep my wits sharp here... and maybe something to break that glow? Yeah, no kidding. Let’s see what’s under that shiny blue armor, then.
What the frame shows. The Choose 1 Mutation menu (Combo, Killer instinct, Vengeance). The big blue figure he means is the Collector, the friendly character who trades cells for upgrades, on screen at 5:28 with his greeting “Well, well, look who’s here.”
accurate He names the biome from the card and answers its question about the smell.
Dead Cells recording at 5:59.
Ah, sliding into the Toxic Sewers now. Lovely, green and deadly, just how I wanted my day to go. That smell? Definitely not normal, but hey, normal’s overrated, right? Well, let’s see if this misty hellhole’s got anything fun in store or just toxic bullsh*t. Here’s hoping I don’t choke on it.
What the frame shows. The loading card “Toxic Sewers — Hmm... is that... is that smell normal?” at 5:56–5:58, then the green sewer level.
inaccurate The bar is not full when he says it, and the hit two seconds later goes unmentioned while he calls it “a real clean hit moment”.
Dead Cells recording at 7:46.
Fully healed, huh? Look at that shock on the slime—this setup’s packing punch real nice. That orange trail, too, means speed’s on point. Feels like a real clean hit moment, like I’m just slicing through whatever’s next. Sewers might be nasty, but not today, no sir.
What the frame shows. The health bar reads about 87% at 7:44–7:47 and falls below half at 7:48 as the player takes a hit in a fight.
Recorded by the developer on an earlier Founder Alpha build (“ALPHA version” in the upload title), not on the current public release.
Dead Cells has no voiced dialogue in this stretch: every quoted line is the Broker’s overlay bubble, and short texts such as “Meh, just some rusty old key” or the Collector’s “Well, well, look who’s here.” are the game’s own.
He is precise where the game prints things (the Equipment screen, the biome card, a full health bar) and loose on fast changes: a hit that halves the health bar goes unmentioned, and a friendly character becomes a threat.
The automatic captions put a speaker-change mark (>>) before “Full health” at 2:02 and “Fully healed” at 7:46; the bubble shows both as his lines, so in this recording the mark does not mean game audio.
Frames extracted from the recording (YouTube -gi1CPmMKGA, 1920 × 804) at 0:06, 2:04–2:08, 3:36–3:44, 5:28–5:42, 5:56–6:06 and 7:44–7:52; the Broker’s words read from his overlay bubble in those frames; timing from YouTube’s audio-derived captions; health levels measured on the HUD bar in the same frames.
What this does not show
The commentary you hear was generated by AI on an earlier Founder Alpha build; wording, timing and voice behaviour change between builds. The current public release is 1.0.0-alpha.12.
A line can be wrong, repeated or badly timed. Quiet stretches are normal: silence is a decision the Broker makes.
This is a recording from the developer’s own play session. It is not a benchmark, a compatibility promise for this game or a measurement of how often he speaks.
The app has no microphone input and no chat: whatever the Broker says is a reaction to what he saw, not to the player’s voice.
