I found a Minecraft server that is basically a full CS2 gameplay experience and you do not need any mods to join.
It tries to copy the important stuff like weapon spread and recoil. It also has wall penetration and grenade physics. The server says the mechanics are made with the original CS2 formulas.
The maps are rebuilt meter by meter so the original timings are kept. Grenade lineups are kept too. It runs on Java 1.21.11.
