Update
Radiant Optimizer games removed: what the DMCA takedown changed
The post that sent people looking for these browser games is gone from X, according to the account that wrote it. Here is what that means and which links still open.
Short answer. The @RadiantOpti account says the "25 games in your browser" post and its links were withheld on X after a DMCA notice from Irdeto on behalf of Activision. We read that on the account's X page on October 19, 2026. Radiant Optimizer, the Windows tuning software, is a separate product and is not affected. The games were third-party projects with their own pages.
What we know, and how we know it
| Fact | Source | Type |
|---|---|---|
| The account posted a list of browser game links that went viral in early October 2026 | Other directory sites; the original post is no longer visible | Reported by others |
| X withheld the post and its links after a DMCA notice from Irdeto on behalf of Activision | The account's own X post | Account statement |
| The Black Ops Zombies link returned HTTP 200 on October 10 and HTTP 451 on October 19 | Our own requests | Observed |
| Why that link now returns HTTP 451, or whether it is tied to the notice | Not stated anywhere we looked | Unknown |

What changed, game by game
We opened every entry page we listed on October 10 again on October 19, 2026, and once more on October 20, 2026. We read the status code, the title and the visible text. We did not play any game.
| Game | Status now | What changed since October 10 |
|---|---|---|
| Black Ops Zombies | Entry link unavailable | The link returns HTTP 451 instead of a page. We no longer link it. |
| Skate 3 | Entry page opens | The fan game page still opens. A second project page we listed now returns HTTP 404 and is no longer linked. |
| Quake | Entry page opens | Both Quake pages still open. |
| Halo CE | Entry page opens | The web port page was renamed Combat Lab. The mobile fan project still opens. |
| CS Surf | Entry page opens | No change. The page still opens. |
What this means for you
- You do not need Radiant Optimizer to play these games, and buying it does not bring them back. The software and the games were never connected.
- Links move fast. A link that opened yesterday can be gone today. Each page here shows the date we last checked it.
- Be careful with "mirrors". When a link disappears, look-alike pages appear. Other directories report that some redirect to unrelated pages. Skip anything that asks you to install an extension, run a .exe file, or enter an account password.
- Some projects need files from a copy you own. Read the entry page's own requirements first. We do not supply or explain how to get game files.
- Publishers can act on fan ports. That is the reason a link can vanish without warning. We do not know which other projects may be affected.

What we will do
We re-check the pages we list and show the date on every one. If a link stops working, we keep the page, mark it unavailable and remove the link. We do not link mirrors or copies we have not checked, and we do not host game files. See the full list and our editorial policy.
