Boxes, health bars, name tags, distance, and state flags on every player, even through walls.

Selyn engine chams on players: wireframe and solid shader modesChams on

Engine chams

Native engine chams with 16 shader modes: wireframe, solid, and forcefield, visible through walls.

Beautiful UI

Frosted Liquid Glass panels, smooth animations, search that jumps straight to any setting, and an accent color you pick.

This is only a few of them. These cards show some highlights, not every feature. Selyn has a lot more inside the client.

Liquid Glass

The menu you can see the game through.

Liquid Glass frosts everything Selyn draws. The menu, the dropdowns, and every overlay blur the live game behind them, so the interface feels like part of the match instead of a gray box on top of it. It is lovely, and you tune every bit of it.

Selyn with Liquid Glass on: the menu, instance explorer, script editor, and HUD overlays all frosted over a Roblox scene
The menu, Dex, script editor, keybind list, target HUD, and velocity graph, all frosted at once.

The real game, blurred

It blurs your actual Roblox window, not a canned wallpaper, and only that window. Nothing else on your desktop shows through.

You set the look

Glass Strength, Glass Opacity, and how often it refreshes. Prefer solid panels? One switch brings them back.

Frosted everywhere

Panels, dropdowns, the keybind list, target HUD, media player, notifications, and the Dex all use the same glass.

Built to stay light

The capture runs on its own thread, refreshes slower while the menu is closed, and you can lower the rate any time.

In action

This is what a match looks like.

A real match with chams, box ESP, the target HUD, and the 3D radar all running at once.

Radar

See the map, not just your screen.

The 3D radar draws the workspace around you, walls and cover included, so you see the angle before you take it.

  • Real geometryIsometric view of the parts near you, rebuilt live from the workspace.
  • 2D when you want itFlip to a clean top-down view with one click.
  • Team filterShow allies, enemies, or both, with facing arrows on every player.

Options in the Misc tab and other aggressive changes can be caught by custom server-side scripts in some games, such as speed limits, flight and noclip checks, teleport verification, and rapid-fire monitors.
