Are there any more proper 3d games like Quake Live that you can play through your browser for free without installing anything?

You're looking for a specific type of game: a fast-paced, 3D shooter that's playable directly in a browser without downloads. While Quake Live is a fantastic example, the landscape for this type of free browser game is limited. Here's why:

* Technical limitations: Building a true 3D game that runs smoothly and is visually appealing in a browser is complex.

* Performance: Browser-based games need to be optimized for a wide range of devices and internet speeds, making it challenging to deliver the same experience as a downloadable game.

* Popularity: Games like Quake Live are complex to create, and without a strong monetization strategy, it's hard to justify the development cost.

Here are some alternatives to consider, though they might not be a perfect match:

* Simplified 3D Shooters:

* Unity WebGL Games: Search for "Unity WebGL" on game portals like Itch.io. You might find smaller, more experimental 3D shooters.

* Browser-Based FPS Games: Some websites offer simplified 3D shooting experiences. Search for "browser FPS" or "online shooter game" for these.

* 2D Shooters with 3D Elements:

* "Doom" style games: Look for browser games that use a top-down or side-scrolling perspective but utilize 3D models for enemies and environments.

* Modern Browser-Based Games: There are new browser-based games being developed using HTML5 and WebGL that are becoming more complex. Check out:

* Game Jolt: A popular website for independent game developers.

* Kongregate: Another popular platform for browser-based games.

* Newgrounds: A long-standing website for Flash games, though they are increasingly incorporating HTML5 games.

Remember:

* Look for games with "WebGL" or "HTML5" in the description to indicate they are compatible with modern browsers.

* Read reviews and watch gameplay videos to get an idea of the quality and gameplay.

While finding a true "Quake Live" clone in the browser might be difficult, you can still discover fun and engaging shooters that offer a unique experience.
