FPS server usually sends raw positional information for all players in the game, and leaves it up to the client's 3D renderer to hide opponents behind walls, in plant foliage, or in dark shadows. If the game map rendering could be turned off completely, all players could be seen moving around in what appears to be empty space. Complete map hiding offers no advantage to a cheater as they would be unable to navigate the invisible map pathways and obstacles. However, if only certain surfaces are made transparent or removed, this leaves just enough of an outline of the world to allow the cheater still to navigate it easily. Asus released wireframe display drivers in 2001 that enabled players to use wallhacks, announcing the settings as "special weapons" that users could employ in multiplayer games. In a poll by the Online Gamers Association, 90% of its members were against the release of the drivers.

Usually, the primary account will be allowed to win through a deliberate lack of resistance from the secondary account(s) due to those accounts being unplayed or those players agreeing to lose. Some players will reverse roles between games, giving each account an equal win–loss record. Disconnecting In games where wins and losses are recorded on a player's account, a player may disconnect when he or she is about to lose in order to prevent that loss from being recorded. This is usually done by activating known in-game glitches or through third-party sources via "IP booting" (a feature of firewall software). Some players do this if they feel their opponent is being unfair. Some games implement a disconnection penalty, usually by recording the disconnect as a loss, a deduction of experience, or even Elo points. Certain games also have a 'disconnect delay' period before the player can disconnect that can last 10–30 seconds. This prevents a player from instantly disconnecting if they are about to die or lose. In some games, if a player disconnects they can receive a warning or even get locked out of online play for a short period.
