Case study: Bang Bop — a browser multiplayer car-combat prototype

The project

Prove a fast multiplayer mechanic runs in a browser

ObjectiveFind out whether the core loop is genuinely fun, and whether real-time multiplayer holds up, before committing to a full game.

TypeInternal prototype (MVP / vertical slice), built to de-risk the mechanic before any full production.

Where it runsIn a web browser. Up to 8 players join one shared arena over a local network (LAN).

What solvX built

The whole vertical slice, end to end

An 8-player arena with driving and drift (handbrake) physics.
Combat & rounds — forward plasma bolts, lives, elimination and round restarts, with a kill scoreboard.
Procedural vehicles — cars defined by JSON blueprints, plus a Vehicle Test Lab to compare them.
Authoritative multiplayer — a Colyseus room server that keeps every client in sync.
Controller support and in-game chat.

Technology & workflow

Browser-native, code-driven, AI-assisted

Everything is browser-native and built from typed, validated components. AI-assisted development sped up building the systems, so the effort went into the feel of the game rather than the plumbing.

What it demonstrates

We can take a game idea to playable

It shows solvX can stand up a complete real-time multiplayer loop — physics, networking, combat and content — and make it genuinely playable in the browser. That's the capability behind any browser game or prototype we'd build for you.

Evidence

The prototype in play

The Bang Bop advert — real gameplay from the prototype. It's an internal vertical slice that runs over a local network, so there's no public live link. Related browser-game work is on the SPLITFIRE page.
