nProtect GameGuard (sometimes called GG) is an anti-cheating root toolkit developed by INCA Internet. It is installed alongside many Asian massively multiplayer online roleplaying games (MMORPGs) such as Rohan: Blood Feud, Lineage II, 9Dragons, Cabal Online, Phantasy Star Universe, GunZ: The Duel, Metin2, Flyff, Rappelz, Luna Online, PangYa, Prius Online, Ragnarok Online, Mu Online and Alliance of Valiant Arms to block possibly malicious applications and common methods of cheating. nProtect GameGuard provides B2B2C (Business to Business to Consumer) security services for online game companies and portal sites.[citation needed]
GameGuard hides the game application process, monitors the entire memory range, terminates applications defined by the game vendor and INCA Internet to be cheats (QIP for example), blocks certain calls to Direct X functions and Windows APIs, keylogs your keyboard input[citation needed], and auto-updates itself to change as new possible threats surface.[citation needed]
Since GameGuard essentially works like a rootkit, players may experience unintended and potentially unwanted side effects. Since the game's process cannot be stopped from the task manager, if the protected game has an infinite loop or hangs in any way, it is effectively impossible to close without logging out or restarting the computer. This is even more frustrating since GameGuard checks if it is already running on the game's launch and does not permit the player to start a new instance in such cases. If set, GameGuard blocks any installation or activation of hardware and peripherals (e.g., a mouse) while the program is running. Since GameGuard monitors any changes in the computer's memory, it will cause performance issues when the protected game loads multiple or large resources all at once.[citation needed]
GameGuard possesses a database on game hacks based on security references from more than 260 game clients. Some editions of GameGuard are now bundled with INCA Internet's Tachyon anti-virus/anti-spyware library, and others with nProtect Key Crypt, an anti-key-logger software that protects the keyboard input information.[citation needed]
Compatibility
GameGuard and X-Trap are explicitly preventing games to run on Windows 10 Technical Preview, even though the operating system is compatible and available for public testing since 1 October 2014.[citation needed]
