Quake browser games: five shooters from one project

Five of the Radiant Optimizer links are Quake browser games in the broad sense: QuakeWorld, Quake II, Quake III Arena, Return to Castle Wolfenstein and Urban Terror. All five come from one non-commercial project on pieter.com, all five are online multiplayer, and none needs game files. They are the most dependable instant-play shooters on the list.

Which Quake browser game to pick

• Quake in browser: QuakeWorld for the 1996 original, Quake II for slower sci-fi deathmatch, Quake III Arena for fast arena play.
• Return to Castle Wolfenstein in browser: class-based World War II objectives on the classic map Beach.
• Urban Terror in browser: tactical team shooter with realistic weapons and wall jumping. Listed in the viral post as Unreal Tournament by mistake.

Why the Quake engine is everywhere

id Software released the source code of its engines under the GPL: Quake in 1999, Quake II in 2001 and Quake III in 2005. Thousands of projects have built on that code since, from Half-Life's GoldSrc engine to Return to Castle Wolfenstein and the ioquake3 engine behind Urban Terror. Open source is what makes it practical to compile these engines to WebAssembly and run them in a browser today.

The engines are free, but the original Quake game data is still owned by id Software. Browser servers like these present themselves as non-commercial, unofficial preservation projects.

How to get a smooth game

• Use a wired connection if you can. These are real-time online matches.
• Turn on hardware acceleration in your browser and play in fullscreen.
• Lower mouse sensitivity in the game menu; browser pointer lock can feel fast.
• Distance to the server sets your ping. QuakeWorld's client-side prediction hides delay better than the newer games.

Quake browser games vs installing the originals

The browser servers are ideal for a quick match on a machine where you cannot install software. For single-player campaigns, mods and full map rotations, the originals are still sold on Steam and GOG, and Urban Terror remains a free desktop download. Status for all five servers is shown on the Radiant Optimizer games list.

The id Tech family tree

• Quake engine (1996): powered Quake and QuakeWorld, and was licensed for Hexen II.
• GoldSrc (1998): Valve's heavily modified Quake engine behind Half-Life and Counter-Strike.
• Quake II engine (1997): later used by games such as Kingpin and SiN.
• id Tech 3 (1999): Quake III Arena, Return to Castle Wolfenstein, Call of Duty (2003) and Jedi Knight II.
• ioquake3: the community-maintained open-source fork of id Tech 3 that runs Urban Terror today.

Your first match in a Quake browser game

Pick a server, click into the game to lock the mouse, and spend the first minute learning where the armor and the strongest weapon spawn. In Quake III, that usually means the Rocket Launcher and the Red Armor. Move constantly; standing still is the fastest way to lose a duel. Strafe-jumping, chaining jumps while strafing and turning the mouse, makes you faster in every Quake game and is worth practicing even if you never compete.

Browser setup for online shooters

Online Quake browser games depend more on latency than on graphics. Close downloads and streaming tabs, use a wired connection where possible, and keep the game tab in focus. If the mouse feels too fast, lower sensitivity in the game menu rather than in your operating system, since pointer lock reads raw mouse movement.

Quake browser games on phones and Chromebooks

All five servers are designed for a keyboard and mouse. Chromebooks handle them well as long as you use an external mouse, because the touchpad makes aiming and pointer lock awkward. Phones can sometimes load the pages, but without touch controls you cannot really play. Tablets with a Bluetooth keyboard and mouse are a workable middle ground on Android; iPads are less reliable because of how Safari handles pointer lock. If a game does not respond to the mouse after loading, click inside the game area once more. Pointer lock only activates after a direct click, a security rule all browsers enforce.
