The October 8 list leans on a family of preservation projects: real classic engines — Quake, Quake II, Quake III, RTCW, Urban Terror, Half-Life and Diablo — compiled or wrapped so a browser can run them. Most are multiplayer builds, not full campaigns.

Source check: October 13, 2026. Not a gameplay test.A LITTLE CONTEXTPreservation,
Preservation,
not piracy.
Several of these hosts state plainly that they are non-commercial museum projects unaffiliated with the original publishers, and some ask for game data from your own copy. That boundary is what keeps them up.
Back to all 25 entries →Why do most classics show multiplayer, not campaigns?+
The pieter.com preservation family documents multiplayer modes with play buttons and leaderboards. Campaign content is a different promise that these entries do not make — check each guide's limits section.
Why do some ask for my own files?+
Engine builds like Xash3D run game logic but do not ship the original game data. Projects that follow this rule ask for files from a copy you own — Diablo Web even offers the old shareware demo as a no-purchase route.
What have you actually checked?+
