These are software packages and modules related to Guild Wars, such as game patches, plug-ins, and third-party programs (including those not officially sanctioned by ArenaNet).

Warning: Always be cautious when choosing to install or use any new software, especially software not inspected by the game developer. Historically there have been many cases of game-related programs that may appear innocuous but execute malicious actions including but not limited to: stealing accounts/items, installing malware, running a trojan, etc.
