what is cs2fow fr?

CS2FOW is a server side plugin for Counter-Strike 2 community servers that fights wallhacks by never sending an enemy's live position when walls or smoke fully hide that player. Since a wallhack works by reading data the game client already received, the plugin's idea is simple: if a player cannot legitimately see an enemy, the server never sends that enemy's exact position to their screen in the first place. Everything runs on the server, so players install nothing and there is no client side modification or extra download involved. The plugin follows a fail open rule: if information about visibility is missing, too old, or uncertain, it shows the player rather than risk hiding someone by mistake. It only works on community or dedicated servers running Metamod Source, not on Valve's official Premier or matchmaking servers. Each map gets a lightweight 3D copy of its solid walls, built ahead of time into a fast searchable format, which the plugin uses to check who can actually see whom without running expensive checks every game tick. It also copies the shape of live smoke clouds as a grid of small boxes, so it can track changing smoke edges, overlapping smokes, and holes torn open by grenades. Custom and Workshop maps work too, as long as their physics can be baked into this format, and a companion map baking service can prepare that data for public Workshop maps. The plugin only hides a small set of visuals tied to a living player, such as their player model, carried weapons, wearables, and any hostage they are carrying. It does not delete the player from the server: hit registration, bullet penetration, damage, and movement all continue working normally, so a hidden player can still be wallbanged. It does not block sound based cheats, radar cheats that rely on other data, or reveal information beyond enemy visuals. Setup involves installing Metamod Source, then adding the CS2FOW package to the server, after which a status command confirms whether map data has finished baking. It is released under the MIT license.
