About DEADUP
A 3D zombie survival shooter in the browser. The page describes it as a free zombie survival arena: you fight endless waves of zombies, unlock weapons and climb a global leaderboard. The arena shrinks as the game goes on, bosses arrive with escorts, and a shop sells weapons of different tiers, such as Shatter and the Void Beam. The entrant's pitch calls it “a brutal browser-based survival shooter where you fight endless zombie waves, survive a shrinking arena, and climb through escalating chaos”, inspired, the entrant says, by the vertical progression and rising pressure of Tower of God mixed with the survival intensity of Call of Duty Zombies. It was made with Three.js for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Cursor as the tool. It finished 239th of 945 entries. Free in the browser, with an on-screen joystick on touch screens.
How it was built
Partially verifiedIn the official Vibe Jam 2026 submission the entrant lists Cursor as the tool and answers Yes to the AI-written field. No devlog describes how Cursor was used or which model ran in it. Several of the game's sound files carry “Elevenlabs” in their names, so some audio was made with ElevenLabs; the sources do not say how the 3D models were made.

Built for the Cursor Vibe Jam 2026 with Three.js (with post-processing bloom and loaded 3D models), with Cursor named as the tool. Scores go to a global leaderboard backed by Supabase. Some sound effects were made with ElevenLabs and ship as files; they are not generated while you play.
