A few weeks ago vbgnt learned to make the store page for a game: the screenshots, the artwork, the listing copy and a trailer. That got my games ready to be looked at. It did nothing about getting anyone to look. So this week the studio got a new tab next to Publish, called Promote, and it does the part that comes after: short vertical videos, Reddit and X posts, a list of subreddits that will actually let you post, and a day-by-day schedule to follow.
I ran it on four of my own games the day it worked. Everything below is straight out of those campaigns.
What a campaign is
You tell it four things. What the campaign is about: a launch, an update (you say what changed, and the agent checks each change is really in the project before announcing it), or anything in your own words, like a Halloween event. How long it runs, from one day to sixty. Where it goes: TikTok, Instagram Reels, YouTube Shorts, a landscape YouTube video, Reddit and X, each its own tick box. And two optional extras, a voice-over and an AI-generated opening shot, both off unless you ask.
Then it runs in the background, like a build, and builds on the game's marketing kit when there is one. My four took between 34 and 68 minutes. What comes back is a calendar: every post written out with copy buttons, the video it uses, a tick box for when you've posted it, and a button that drops the whole schedule into your calendar as reminders.
The videos are the game
The shorts are cut from real gameplay. If the kit made a trailer, the agent cuts from that footage. If not, it records the game itself, using Godot's movie-maker mode on a scratch copy of the project, 30 frames a second with the game's real sound, while a script plays it. It records a library of shots once and cuts every short from it, because rendering is the slow part and recutting is cheap. And one file goes everywhere: the same vertical short is the TikTok, the Reel, the Short, and the video on X and Reddit. Only the caption changes. I made that a rule after realising the obvious alternative, a render per platform, turns a forty-minute job into a three-hour one.
A short is built for a phone, not a cinema. The hook is on screen in the first second, a few fast beats follow with big burned-in captions because most people watch muted, the best moment comes last, and the final frame cuts back to the first so it loops.
The AI opener, and saying so
The opening shot was the fun part. Each campaign ran on one joke: the dungeon's staff commuting to work, a cat lady who wants to know how many cats one person can carry, a future immortal who still has a commute, a witch with a takeaway coffee on her way to her potion-piling shift. With the AI hook ticked, the agent opens a short on a few seconds of generated live action built around the game's own characters (it uses a MiniMax video model on fal), then cuts hard to the real game.
There are rules around it, because this is exactly the kind of thing that goes wrong quietly. The opener is capped at five seconds and never more than about a third of the short. It can't look like gameplay: no interface, no mechanics the game doesn't have. And it's disclosed. Every post that uses one carries a note telling me to switch on the platform's AI-content label when I post it, and the plan marks the video. The captions went further than I asked. The Dungeon Spin TikTok caption reads: "Intro is AI, the rest is the real game."
The voice-over is optional too. It uses Gemini's text-to-speech when there's a Gemini key and a fal voice when there isn't, reads as an excited creator talking about their own game rather than a movie-trailer announcer, and puts the hook out loud in the first second.
Reddit, done the way Reddit wants
This is the part I was most nervous about, because the easy version of it is spam. The agent searches for subreddits that fit the game, then reads each one's rules, posting requirements and activity through Reddit's API. That needed a proper API key: Reddit now refuses anonymous requests even from my own laptop. Subreddits that ban self-promotion or AI-made games get dropped, and listed, so I don't try them. For Dungeon Spin it kept eleven and posts to seven, one a day, and the notes are what make it useful: r/playmygame wants the game free to play right now, r/aigamedev wants the post to be about how the game was made.
The posts are maker posts. "I made Dungeon Spin, a free browser bubble shooter where every hit spins the horde." The first comment says I'm fixing things this week and asks for "this felt unfair" notes. No pretending to be a player who found it, no vote-swap suggestions, no invented numbers, and Reddit and X are never posted automatically. I post those myself.
Changing it, and the day I scheduled ten posts at once
A campaign is a draft, not a verdict. Revise takes feedback on the whole thing, on one post, or on one video: every video and image has a "Change this" button, so "make the hook text bigger on this one" goes to that file, and the agent keeps the file name so every post using it picks up the new version.
For the TikTok, Instagram and YouTube posts, the studio can also schedule them for me: I connect a post scheduler once in Settings, tick the posts I approve, pick which of my accounts each goes to, and the agent books them at their planned times. Nothing goes out without that approval.
Then I started all four campaigns on the same day and found ten posts landing on it. So now posts move too, at any time: one post, everything on a crowded day, or the whole campaign, and anything already booked moves in the scheduler as well. That feature exists because of my own schedule.
Your agent can run it
vbgnt is also an MCP server, and Promote is in it now, so Claude or any agent you connect can plan a campaign, revise it and move posts around. Scheduling to real accounts is the one place I made it stricter than everything else: the agent has to ask you which accounts to use, show you a preview of every post, time and account, and only schedule after you say yes. It publishes in your name, so you should be the one who decides where.
