Marvel's Project Comet Leaks: A Gacha Open-World RPG With Four-Player Co-op and PC Crossplay
On October 5, a gameplay trailer for an unannounced Marvel game codenamed Project Comet surfaced on the Chinese video site Bilibili before being reposted to YouTube . It shows real-time combat, cooldown-based abilities, open-world exploration and a four-player team structure. As of October 7, neither Marvel nor the publisher has acknowledged that the game exists. The leak matters less for how it looks than for what it moves: a project rumoured for months has jumped from concept art to something that resembles a playable build. The footage includes Scarlet Witch, Wolverine, Spider-Man and Doctor Strange, with combat pacing close to Genshin Impact, and the Bilibili description references "collectible Marvel characters" - the tell of a gacha system. Platforms point to Android and iOS.
一、The leak itself: a trailer where nothing syncs
Start with the caveat. Polygon noted the video's "audio is completely off, with an awkward voice-over and de-synced sound effects," and that it ends abruptly, which points to a work-in-progress build rather than a finished marketing asset .
The twelve-character roster from an earlier leak
An earlier leak from X user MultiverSusie, whose post has since been deleted, showed in-game animations and concept art and alleged a launch roster of twelve heroes: Captain America, Elektra, War Machine, Invisible Woman, Wolverine, Spider-Man, Doctor Strange, Juggernaut, Doc Ock, Quicksilver, Beast and Thor .
The names are informative. War Machine, Juggernaut and Doc Ock are not the characters a film marketing team would prioritise. They read like a fan-service collection pool, which is exactly the shape a gacha roster needs.
二、The shape of the game: four-player co-op, gacha, open world
Journalists' accounts converge on a similar picture: a free-to-play open-world action RPG with replayable four-player co-op missions and crossplay between mobile and PC . Recruitment material indicates a closed playtest for iOS and Android users around June 2026 .
Like a mobile Marvel Ultimate Alliance
Insider Gaming draws a concrete comparison: the design leans on the Marvel Ultimate Alliance series, with four-player teams, repeatable missions and higher difficulty tiers offering bigger rewards . Multiple outlets also noticed that leaked character models closely resemble their Marvel Rivals counterparts, reportedly because some artists who worked on Marvel Rivals are contributing to this project.
三、Who is building it: Scopely and its backers
Every thread points to one name: Scopely. The studio has operated the Marvel licensed game Marvel Strike Force since 2017, and in 2025 it acquired Pokémon Go developer Niantic in a $3.5 billion deal . A job posting surfaced by reporter Sarge fits: it describes an "unannounced ARPG mobile title based on a major IP" and lists experience working with Chinese game studios as preferred.
The money behind it is just as loud
Scopely is funded by Saudi Arabia's Public Investment Fund. According to Polygon, the PIF finalised a $55 billion purchase of EA in August 2026 . Put those two numbers side by side and the framing becomes obvious: this is Middle Eastern capital placing a direct bet in the mobile market.
Scopely's catalogue explains the fit. It publishes or operates Monopoly Go, Star Trek Fleet Command, Stumble Guys, Monster Hunter Now and Pikmin Bloom alongside Marvel Strike Force . A team with that many licensed live-service titles already has the monetisation machinery an ARPG gacha needs before a single line of combat code ships.
四、Why Marvel would build another Genshin
The answer is written in revenue curves. The open-world gacha model has been proven for nearly six years, and Marvel holds the most globally recognised character library in the medium while still lacking a genuine long-term open-world product. Previous Marvel mobile titles have been card battlers, strategy games, or PvP-focused.
The second reason is the sample Marvel Rivals provided. NetEase's team shooter proved how efficiently Marvel characters convert among younger players, and the detail about models resembling Marvel Rivals suggests that at least on the art side, someone is reusing a visual language the market has already accepted.
五、The cold water: a leak is not a launch
Be clear about this. There is no title card, no platform announcement, no release window, and Scopely has not responded to the leaks. Between a playable build and launch sit monetisation design, publishing approvals and regional rollouts. The earlier a leak arrives, the more room there is for delay. MobileGamer.biz notes that Scopely has not commented and that its public job listings frame the project only as an unannounced ARPG mobile title based on a major IP - a description that fits several possible properties.Follow overseas studio moves at GameHub.
六、What is and is not confirmed about Project Comet
Is Project Comet an official project?
Not officially announced. It exists as a trail of leaks and job listings, unconfirmed by Marvel or Scopely . Treat official channels as the only authority.
Which platforms will it launch on?
Leaked material indicates Android and iOS with mobile-to-PC crossplay. No platform has been confirmed officially.
