## An arena shooter built for repeated matches

Quake III Arena concentrates on fighting other combatants in compact science-fiction and gothic arenas. Weapons and power-ups are central to that contest, so learning where to move can matter as much as keeping your aim on an opponent. It suits a session built around repeated rounds and improving your route through a map, rather than following a story campaign.

The commercial package includes a broader set of arenas and the Team Arena expansion. Those retail-package features should not be confused with the demo-data browser route offered here.

## Q3JS and its demo-data client

Q3JS uses an ioquake3 WebAssembly build and the officially released demo data. The launch path is multiplayer: choose a live server, enter a player name and join. That keeps the immediate decision focused on where to play rather than on importing a retail installation.

The separate server-hosting instructions are for operators. Their retail-data requirements do not turn the hosted player client into a full retail Quake III installation. Use the server list as the starting point for this version.

## How the phone layout changes the session

On compatible phones and tablets, Q3JS automatically presents touch controls. Movement belongs to the left joystick; the right side handles aiming, firing, jumping, crouching and weapon changes. Scores and menu controls are included, so you can check the match without looking for desktop keys.

Rotate to landscape before settling into play. Fullscreen is available only where the browser supports it. The split between movement and aiming means both thumbs are busy, so it is worth learning the jump and weapon buttons before trying to follow a fast opponent around an unfamiliar arena.

## Do I need the original game files?

The hosted Q3JS client supplies the officially released demo data. Its separate server-hosting guide asks server operators for retail pak files; that is not the hosted player setup.

## What are the controls?

On touch screens, the left joystick moves and the right side provides drag-to-look aiming, fire, jump, crouch and weapon switching. Scores and menu buttons are included.
