About Open Saber

Step into a pulse-pounding world of rhythm and precision in Open Saber, the ultimate free online VR adventure crafted fresh for the browser! This indie gem, born from the community-driven fork of Beep Saber by NeoSpark314, harnesses the raw power of Godot 4.3 and OpenXR to deliver an exhilarating rhythm-slashing experience that puts you right in the heart of the beat. Designed for players who crave that perfect mix of adrenaline, immersion, and indie spirit, Open Saber offers a fast-paced gameplay loop, responsive VR controls, and a performance-optimized engine compatible with almost any device running OpenXR or WebXR.

From the very first beat, you’re plunged into a neon-lit world where the music comes alive around you. Armed with your trusty saber and standing at the center of a digital stage, you slash glowing blocks in perfect sync to the pulse of electrifying tracks like “Time Lapse” by TheFatRat. Whether you’re playing on PC VR, Quest, or pushing the limits of your browser in WebXR, Open Saber lets you chase high scores, hone your reflexes, and lose yourself in the flow state only top-tier rhythm games deliver.

Serious tweaks and quality-of-life updates set Open Saber apart: a slick new user interface, smoother framerates, and fast-loading gameplay ensure you spend less time waiting and more time conquering the rhythm. Even on browser and mobile, the game pushes performance boundaries, allowing you to take your VR adventure on the go. Indie touches like built-in song support, customizable settings, and community-driven mods mean there’s always something fresh to master. With medium difficulty, Open Saber hits the sweet spot for both rhythm game newcomers and seasoned beat-sabers, constantly tempting you back for just one more song.

Dive in free, feel the beat, and show the world your moves — Open Saber is more than a game, it’s a high-energy, VR rhythm adventure you’ll want to play again and again.

How to Play

Getting started with Open Saber is a breeze if you have access to a VR headset (HMD) and controllers. Begin by launching the game in your browser or VR-enabled device — make sure your setup supports OpenXR or WebXR for best results. After the quick initial load, you’ll be transported into a vibrant, neon-lit arena. Use your motion controllers to grasp your virtual sabers. As the music starts, colored blocks will stream toward you in sync with the beat. Your goal: slice each block in the indicated direction using fast, accurate swings of your arms, matching your movements to the rhythm.

Keep an eye out for directional arrows and avoid slicing with the flat side — clean, on-beat hits score the most points and rack up your combo multiplier. Missed beats break your streak, so stay focused and let the music guide your flow. The game’s UI makes selecting songs and tweaking difficulty intuitive, even for those new to VR rhythm games. While there’s a slight performance dip on first launch (especially in-browser), gameplay quickly smooths out, providing tight feedback and real-time scoring. For mobile or Quest play, ensure you have a stable internet connection and enough room to move safely; clear your play space to maximize immersion and minimize distractions. Beginners should start on medium and take it slow, focusing on accuracy and form before ramping up speed. Master your timing, anticipate block patterns, and don’t be afraid to replay tracks for that perfect score — Open Saber rewards both skill and persistence.
