Play Sonic Adventure DX in Browser

Sonic Adventure DX Browser Edition is an unofficial web version available on Khelbo. It is not the original game and is not made by, endorsed by, or affiliated with its original publisher or developer. Speed into the golden era of 3D platforming when you play Sonic Adventure DX browser edition on Khelbo. Originally released for the SEGA Dreamcast and later enhanced as the Director's Cut, Sonic Adventure DX redefined the blue hedgehog with expansive open-world Adventure Fields, six playable character campaigns, and high-velocity loops. Through web emulation, this platforming epic runs natively in your browser tab with zero downloads or emulator setup.

Experience the narrative from six unique perspectives. Blaze through high-speed loops with Sonic, fly and race through checkpoints with Miles "Tails" Prower, glide and hunt for shattered Master Emerald shards with Knuckles the Echidna, evade the relentless ZERO robot with Amy Rose, fish for Froggy with Big the Cat, and blast targets using E-102 Gamma's lock-on laser cannons. Completing all six campaigns unlocks the climactic Super Sonic finale.

Sonic Adventure DX balances thrilling Action Stages with interactive Adventure Fields. Roam the bustling modern metropolis of Station Square, explore ancient tribal ruins in the Mystic Ruins jungle, and board Dr. Eggman's flying fortress, the Egg Carrier. Iconic Action Stages like Emerald Coast—featuring the jaw-dropping killer whale pursuit—and Speed Highway deliver unforgettable platforming thrills.

Beyond the main action campaigns, Sonic Adventure DX features the beloved Chao Garden virtual pet simulator. Find hidden Chao Garden entrances in each Adventure Field, hatch cute Chao from eggs, and feed them animals and Chaos Drives gathered from Action Stages to boost their flying, swimming, running, and power stats for the Chao Races.
