Two ports of the same game, built for two different kinds of headset
Counter-Strike 1.6 can be played in a VR headset two ways, and which one you want is decided by the headset you own rather than by taste. CSVR, by Team Beef, is a standalone app for Quest and Pico headsets that you sideload and feed with your own copy of the game. The port on this site runs in a browser on a PC with a VR headset attached, needs nothing installed and no copy of the game. Both are the same 1999 game with the same maps and the same servers on the other end; they differ in everything about how you get in.
Try the browser port (PC VR)Step-by-step: entering VRTeam Beef are the team behind a long line of VR ports of classic PC shooters for standalone headsets, and CSVR is their port of Counter-Strike 1.6, released through SideQuest on 11 January 2026. It is the reason "Counter-Strike VR" became a search term at all this year.
The browser port on this site is a different distribution of a closely related thing. The game itself was already running here in a browser through WebAssembly; the VR layer added to it is a port of Team Beef's own CS VR game logic, so the aiming model, the two-handed weapon handling and the comfort options are theirs. What was written fresh is the part that lets a browser hand the game to a PC VR runtime. It is fair to say one would not exist without the other.
CSVR supports the standalone headsets Team Beef list on their install page: Meta Quest 2, Quest Pro, Quest 3 and 3s, and the Pico Neo 3 and Pico 4 families. It runs on the headset itself; once installed, no PC is involved.
The browser port supports headsets a PC drives through SteamVR or another OpenXR runtime, which is the Valve Index, HTC Vive, Windows Mixed Reality, Pimax and similar, and in principle any headset that runtime already shows a picture in. It does not run on a standalone Quest from the headset's own browser. If you own a Quest and want to play without a PC, CSVR is the only one of the two that applies to you.
CSVR needs a copy of Counter-Strike 1.6 that you own, installed on a PC, because the app ships without the game's content. The install page has you sideload the app with SideQuest, launch it once so it creates a folder on the headset, then copy the game's two content folders from your Steam library onto the headset by cable. It is a one-time job of perhaps fifteen minutes, and a PC is required for exactly that long.
The browser port needs nothing owned and nothing copied. The game content is fetched by the browser tab as you play, cached after the first load, and the maps stream on demand. There is no app to sideload because there is no app.
CSVR can host a server from inside the headset for local and internet games, and it joins servers hosted by other CSVR players; Team Beef's page notes that hosting works best on a connection with a permissive NAT and offers a fallback when it is not. Cross-play with the Android version of the same engine is listed as supported.
The browser port joins the public Counter-Strike 1.6 server list, the same servers the flat browser version and everyone else on the internet plays on, through the site's own relay. You are not in a VR-only pool; the other players are on monitors. Whether a server is told you are in a headset is a switch in the settings. Whether a headset-hosted CSVR server can be joined from here has not been tested, so it is not claimed.
Because the VR game logic is shared, the feel is shared: aim by pointing the weapon, brace with the off hand for two-handed aiming, snap or smooth turning, walking relative to head or controller, room-scale movement within about a metre. The browser port exposes twenty-eight settings for all of this in its VR panel, including per-button rebinding, render scale, world scale, arm length and a comfort vignette. Team Beef's port has its own settings surface inside the app. Neither is the thin option here.
CSVR: it is standalone only, so a PC VR headset has no way in, and it depends on you owning and transferring the game. The browser port: no standalone play, no Sven Co-op in VR yet, no screenshots during a session, and one known oddity where PCs with two graphics adapters reload the page once on the first Enter VR. Both are community projects with no connection to Valve, and neither is a product you can buy support for.
Quest or Pico, and you want it on the headset with no PC in the loop: CSVR, and follow Team Beef's install page. A headset that plugs into a PC: the browser port, and the how-to guide linked above takes about five steps. A Quest that you already use for PC VR through a link cable or streaming should in principle be the second case, but it has not been tested here and this page will say so until it has.
