Quick summary
A top-down take on Dust2. It’s a raycasting shooter where you read the iconic map from above and trade fire in fast rounds. The game is light and starts instantly, and you can replay it endlessly in any browser.
Who this template is for
This build takes a map everybody already knows and changes the camera. It’s for people who want a fast game and a compact rendering lesson at the same time.
- Developers who want to see raycasting, the classic technique behind early first-person games, applied to a top-down view
- Studios needing a lightweight playable that loads instantly on any machine and any connection
- Anyone building tactical or top-down games who wants a working sightline model to study
What problem this template solves
Most “browser games” on offer are either heavy engine exports or toy demos that fall apart the moment you look under the hood. This build is neither.
- Engine exports ship megabytes of runtime before the first frame ever draws
- Toy demos skip the hard parts: real collision, game states, difficulty curves, and persistence
- Builders who want to learn from a finished game almost never get to see the instructions that produced it
What you get with this template
You get a fast top-down shooter that renders the Dust2 layout and its sightlines in real time on the canvas.
- Overhead play on a recognisable competitive map, so orientation is instant for anyone who has played it
- A raycasting engine computing visibility and sightlines every frame rather than faking them
- Short, repeatable rounds made for quick sessions
Page sections overview
| Section | Purpose |
|---|---|
| Raycast sightline engine | Compute what is visible from the player position every frame |
| Overhead Dust2 layout | Present the recognisable map from above so orientation is immediate |
| Fast round structure | Keep rounds short so sessions stay quick and repeatable |
| Lightweight canvas rendering | Keep the whole build tiny so it starts instantly anywhere |
| WASD and mouse control | Use the movement and aiming model players already have |
Design and branding system
The look is a tactical readout: a sand-toned map surface, high-contrast player and sightline marks, and no ornament competing with the geometry.
- A sand-and-shadow map palette with player and threat marks pushed to maximum contrast against it
- Sightlines drawn as the primary visual element, because visibility is the subject of the game
- A minimal interface that stays at the edges and leaves the map unobstructed
Mobile and speed optimization
The game targets desktop first, with keyboard and mouse as the primary controls. It stays light enough to load instantly anywhere.
- There’s no engine runtime and no asset downloads, so the whole game arrives in a handful of requests
- A capped frame delta keeps the simulation stable even when the browser tab stutters or loses focus
- The page stays lean, with no frameworks or trackers between the visitor and the game loop
How this template helps you convert
A playable game holds attention longer than any showreel. The page around it is built to turn that attention into a next step.
- Visitors play right away, with no signup, download, or install before the first round
- The finished build is fully inspectable, which turns curious players into builders who want the prompt behind it
- Paying once for the prompt is a small, concrete next step while the session is still hot
Other information about this template
A few notes before you adapt this build.
- It’s a tribute build for demonstration purposes and isn’t affiliated with the original rights holders
- Keyboard and mouse are required, so it targets desktop rather than touch
- The map is data the renderer reads, so swapping in your own layout doesn’t require engine changes
- It’s the lightest game in the library and the fastest to load on constrained connections
How it works
A raycasting engine draws the map and sightlines in real time on the canvas. It’s a classic technique, and it keeps the game fast and tiny while it still feels like a shooter.
