And Quake 3: https://thelongestyard.link/q3a-demo/

And Unreal Tournament: https://dos.zone/mp/?lobby=ut

There's also https://noclip.website/ which, while not playable, has hundreds of levels from dozens of older games that you can explore freely. Including Half-Life 2, with more accurate rendering than this web port (which seems to be missing many shaders including character eyes).

Also The Simpsons Hit & Run! https://shar-wasm.cjoseph.workers.dev/
And Tomb Raider

Fan remake of the levels to avoid asset copy, but it's a downstream of the original engine (and loads the original level files just fine), so the real game.

Ha fun--works in my regular laptop in Chrome without any CPU/GPU etc spikes
I vibe coded this for exploring levels in the original Deus Ex: https://dxwebview.pages.dev/ (https://github.com/addrummond/dxwebview).

It's a bit janky owing to the vibe coding, but the basic functionality works pretty well. You need the original game data files to use it.

What a time to be alive
Interesting, I am not able to play HL2 on Steam because macOS no longer has 32-bit support and Valve never compiled if for 64-bit but here we are, it’s playable on the same OS in the browser.

BTW IIRC there was some method to convert the 32-bit game binaries to make them run on recent macs. I remember doing it.

I admit that Valve’s approach to Steam on macOS has never made sense to me.
This was more Apple's doing rather than Valve's.

Valve wanted steam to co-exist on the mac in the early days and John Sculley of Apple didn't want Apple to be seen as a gaming device or a "personal home computer". So they ceased contact with Valve and the rest is history. https://www.youtube.com/watch?v=lPTLPXNtb2I

Apple refused to license joysticks so they could prevent customers from considering early mac's as game machines and deliberately refused to support games on the machine. Myst was only few that were exclusive to the Mac; that they then ported to PC.

On paper qemu should be able to do this. The hard part is hardware acceleration for the GPU. Without Apple putting effort into supporting this with e.g. documentation, that's a bit hard. That's also holding back linux support on Apple hardware. But it's a fixable problem that will only get easier as hw gets better and faster over time.
> The hard part is hardware acceleration for the GPU

Is it, though?

How Hard Can It Possibly Be to just do a software GL renderer that emulates a mid-2000s Radeon, these days?

At what resolution. You're not going to software render 4K120FPS even with 2000s graphics. But you also don't need a software implementation since translating to a host API isn't really any harder than that (and often much easier). And this already exists in Wine.
Here is a link to the blog post since I didn’t see it mentioned

Yeah probably better to link to this instead, else everyone clicking will start downloading the big files.
This is cool, and also probably illegal, since you don't own any of this and don't have the right to redistribute it.
Valve already gave Half-Life 2 away for free, and released the source code of the HL1 engine.

Is it technically illegal? Yeah, but Valve isn't losing out on any money, and there's no way they're going to risk the negative PR blowback they'd get for a takedown.

Besides, IP law is dead. The rise of AI made it pretty clear that you can steal literally anything without consequences.

Giving things away for free (at one point) is not the same as making it public domain or relinquishing your (copy)rights. Source available is not the same as open source. Open source code does not mean open source assets/product. I find it weird that this needs to be explained in this community.
GoldSrc (HL1 engine) is very much not open source (or even source available). There's at least one open source remake (which is possibly illegal due to using the SDK) but no official release.
>Besides, IP law is dead. The rise of AI made it pretty clear that you can steal literally anything without consequences.

God, AI keeps making life better than I could've ever imagined!

It only works like that for the Big Thieves. Us regular folks get screwed over just like before.
No no, you can't steal anything without consequences, only big corperations who are making slop machines(tm) can.
Turns out "too big to fail" doesn't just apply to reckless financial behavior.
This project seems perfectly congruent with current year industry standards regarding copyright, which are to move fast and lobby for permission later.
That is up for the copyright owner to enforce or not to enforce.

Until they decide, we can't know if it's illegal or not - who knows, this site might have a license.

A crime is a crime even before a judge rules over it. Sure, innocent until proven guilty, but most people know when they're doing something wrong and then don't do it.

Of course, this is a lot more grey area for copyright violations etc because it's a civil matter.

It's not legal just because the copyright owner doesn't immediately sue you.
Technically it isn't illegal until the copyright holder decides not to grant (retroactive) permission.
If a copyright infringement falls in a forest and nobody is around to hear it, did it make a sound?
It's quite dangerous to make unsubstantiated comments and assumptions on US copyright law without the proper research.

Valve still owns the copyright to the game and just because they won't do anything now does not mean it is legal to redistribute it without their consent, especially when we know that the game is still being sold. [0]

They (Valve) reserve the right to enforce that and this site clearly does not have such a "license" and haven't disclosed as such. Why would you expect Valve to be in discussions with a 15 year old to redistribute the game for free?

So just say you do not know.

> Why would you expect Valve to be in discussions with a 15 year old to redistribute the game for free?

Because projects like this are free publicity and don't actually compete with the product sold on Steam.

> just because they won't do anything now does not mean it is legal to redistribute it without their consent

I don't think the parent comment is claiming it's legal, other than the (unlikely) chance that this is licensed, just that it's up to Valve to enforce and not really our concern. A lot of cool things (like the similar https://noclip.website/) are prima facie copyright infringement.

> we can't know if it's illegal or not

I think we can.

We can guess this is unlicensed, and likely be right, but whether it gets taken down is up to Valve.
And I think we don't care.
That's also the kind of Website, beside the impressive technical result, that reminds me nothing can be blocked.

It's not about bypassing VPN or deep pack inspection, rather it's about how once anything, including a very complex video game (like here) to an entire OS with a host machine (like QEMU on WASM, or a random InternetArchive link about emulation) is "just" a Web page that can be hosted... on anything (including a 10 bucks Rasperry Pi Zero which can also be an AP, a phone obviously, heck even a e-cig!) then it doesn't matter what is "blocked" as it can be brought to anyone with no installation.

Sounds like companies should start locking down browsers to disable WebGL, WASM and other similar APIs targeted at apps as opposed to web pages. I would welcome this if it got web developers to stop using more than they actually need.
Whew. Crashed before I sunk my day there.
I just wish Valve could add official macos-arm64 builds of the various hl2 games on Steam :-/
Very cool. The download progress bar is broken though, it receives values 0-1 but the max is set to 300.
As much as I dislike webdev stuff, I love the way you can distribute entire programs through WASM. Super cool stuff! For those who are interested, I recommend checking out Godot for exporting games on the web. It's really easy to do and you can host it on Itch.io
First half life one in browser now we have half life 2! I guess it’s that time again Mr Freeman
What's the biggest bottleneck you hit - GPU compute, memory bandwidth, or network latency for asset streaming? Curious how it compares to native WebGPU.
The screens are missing and the lips don't move, but it's pretty close!
The blog post mentions that the animation system was disabled, because it caused a lot of issues
If they have halflife 2 in the browser, I wonder if this means they can do original CS in the browser too!
What about gaming on a mac?
Is there a repo for this ? Can we mod it ?
Ah! Just in time for HL3
Along with Team Fortress 3 and Portal 3 ofc. :)
I remember saving up for a year to buy the ATI Radeon 9600 XT (I think it was $200 MSRP) so I could play the game on high settings. Now we can play it inside a virtual machine on a crappy laptop. What a journey
I was just going to say the same thing. I couldn't afford the rigs needed to run any of these games and never really played them. Now, it's running inside a browser on a laptop.
Same here - splashed out crazy money upgrading my PC to play HL2.

After that moment I switched to consoles.

In a few years todays high end AI models will run on your watch

Of course that assumes we maintain open access to compute that we've enjoyed for the last half century, and I doubt that very much.

Stallman warned about the dangers of software being closed [0] 30 years ago, and the majority of modern IT industry just laugh a that sort of stuff because you can't make a billion dollar startup with that attitude, but I think the restrictions on owning the hardware at all will probably come first.

What a time to be alive :D
Looks pretty good
play-cs.com
What I find incredibly impressive is that it just loaded in and seems to work fine on my phone. So cool.
Cool, but then game hangs in city square.
I've played this from the start until around Ravenholm probably close to a hundred times. It's so familiar to me. There's some funky stuff going on for me, though. The characters' eyes are all wrong. G-man had no eyes at all. And the giant screen with Breen on it was missing.

Can't believe it runs as well as it does on my non-gaming laptop without even seeming to struggle. It's funny when you leave a hobby for a while. I haven't played games since the HL2 era so for me this is still state of the art.

I did say a couple of years ago that if HL3 ever came out, and it was good, that it would make me buy another gaming PC. But with current prices I don't even think that would make me do it.

Tried it on my M4 iPad Pro and was surprised that it works - to a degree. NPCs (Gman and the citizens on the train) seem to be missing eyes and have no mouth animations. FPS was pretty poor too, and it was ass to use the camera on the trackpad.
While technically impressive, this is also illegal. (unless you have redistribution permission from the authors.)
Yup. I was going to finally buy half life 2 today but now I’ve seen this I guess I won’t need to.

Hard times at Valve, I suppose they’ll have to find more children to start gambling with them.

looks like you forgot to add /s tag to your comment :swh
But what about the people who aren't idiots and can read sarcasm without the /s? I reflexively downvote ever comment I come across with a /s. People aren't idiots until you treat them like one.
But what about people who are in different parts of the world and don't inherently understand your meaning? That is terrible behaviour to downvote the notation.

Text is notorious for not conveying context. Sarcasm can easily be seen as serious by some people, why is why we have the /s notation to make it obvious.

People aren't idiots, they come from different backgrounds, locations, languages, and all use English as a common tongue. Have some consideration and stop thinking you are so big and clever.

lmao :)
Someone has to look out for the big guys! /s
> this is also illegal

So is unregulated gambling but Valve doesn't care either lol

2 wrongs don't make a right.
Ah yeah the famously equal acts of pirating a game VS promoting illegal unregulated gambling for millions of people (and that's just the tip of the iceberg).

That's why corporations can get away with everything.

Is that why I can't access the site?
It works on chromium-based browsers at least
In which jurisdiction?
Every signatory of the Berne convention or member of the TRIPS agreement, and most others too.
legality != morality
