一段疑似漫威未公布新作《彗星計劃》（Project Comet）的實機預告片在網路上大規模泄露，揭示了這款免費動作RPG的核心玩法與角色陣容。截至發稿，漫威官方與據傳的開發商Scopely均未對此作出任何回應。
從泄露畫面看，遊戲採用實時手動戰鬥模式，螢幕配有虛擬搖桿和技能按鍵，每位英雄擁有多個主動技能和一個專屬終極技。任務圍繞四人小隊構建，高難度副本可重複挑戰以獲取更好獎勵。場景涵蓋了霓虹都市街區與帶有魔法符文元素的奇幻要塞。
MARVEL ARE CREATING A WUTHERING WAVES / GENSHIN IMPACT COMPETITOR! Project Comet is a free-to-play mobile ARPG built around Marvel heroes and villains. Testers described it as a Genshin Impact / Wuthering Waves-style Gacha with real-time combat, crossed with Marvel Ultimate Alliance’s squad missions. In terms of platforms: Confirmed in the test materials were iOS and Android. Later trailer posts and a Russian write-up of the Bilibili footage claim PC cross-play as well. Console versions have not been mentioned. Store badges in the trailer material point at Google Play and the App Store, but specifics are not yet available. In terms of gameplay: It features manual control, not auto-pathing. On-screen stick plus ability buttons, with several skills and an ultimate per hero. Missions are built for a four-player co-op squad and can be replayed on higher difficulties for better rewards. Environments shown so far include neon city blocks and more fantasy-looking strongholds. Characters confirmed so far: S-rank: Wolverine, Doctor Strange, Captain America, Doctor Octopus A-rank: Invisible Woman, Elektra, Spider-Man, War Machine Closed test invites went out in early June 2026. THIS COULD BE MASSIVE! .. OR A MASSIVE FLOP. Only time will tell! https://twitter.com/ByteStix/status/2107114058067403094
多方資訊指向該作由Scopely開發，即《寶可夢GO》的現東家。Scopely此前已與漫威有過合作，開發過《漫威神威戰隊》。據稱，《彗星計劃》定位為免費遊玩、跨平台（PC與移動端）的開放世界冒險遊戲，支持iOS、安卓與PC之間的跨平台聯機。
在官方正式發聲之前，關於《彗星計劃》的一切仍停留在傳聞階段。
