Epic Games AI MegaJam: $22,500 UEFN Contest [Confirmed]

Epic Games has officially launched the Unreal Engine AI MegaJam, an open competitive development hackathon offering $7,500 top prizes across three dedicated categories for developers utilizing unlimited artificial intelligence agents to build playable games in Unreal Engine and UEFN throughout 2026. According to verified reports from Destructoid, the contest invites teams of up to four human creators to pair with an unrestricted number of autonomous AI agents, whether building remotely across global regions or on-site at San Francisco's Digital Jungle alongside partners like Anthropic. The initiative follows Epic Games CEO Tim Sweeney's aggressive push into machine-assisted software generation, often colloquially dubbed vibe coding, following recent experimental redesigns across the Epic Games Store storefront. Participants can deploy artificial intelligence across code generation, asset fabrication, and level design frameworks to produce fully functional prototypes. While traditional software engineers express skepticism regarding automated production pipelines, Epic positions the initiative as an evolution for fast prototyping within Fortnite creative ecosystems and standalone indie development, testing how rapidly modern algorithmic tools can assemble commercially viable entertainment under tight hackathon deadlines.
