AI Cloning Fears Force Digital Sun to Cancel Public Playtest for ReVamp

Digital Sun has cancelled the public Steam playtest for its upcoming game ReVamp due to concerns that AI tools like Claude Opus 5.5 could reverse-engineer and clone the game before its March 2027 release. The playtest will now be limited to a smaller group via Discord. The developer cited recent incidents where games were decompiled, cloned, and published online using Anthropic's LLM, a process that previously took months or years. Digital Sun apologized for the change and hopes to open the public playtest around January, with Discord signups available before October 29. The move reflects broader industry anxiety, as Alliance Arts also cancelled a Next Fest demo for similar reasons. While Steam's Next Fest features over 8,000 demos, larger playtests are now seen as high-risk, raising questions about how studios can safely showcase early work.
