Features

By default, PerfectGuard does the following:

• Applies rate limiting to abusable network calls, preventing DoS attacks from excessive particles, visuals, audio, etc.
  • The mod will log suspicious players / game objects in the BepInEx console
• Applies rate limiting to audio sources, preventing the same audio source from playing too many clips at the same time
• Cleans up excessive items when there are too many of them at the same time in the server
  • The item threshold can be configured to be anywhere between 50 and 500 total items
  • Currently applies to server hosts only

Each of these features can be toggled on or off either via the configuration file of the mod (BepInEx/config/Marioalexsan.PerfectGuard.cfg) or via EasySettings (if available).

For some features, detailed logging can be toggled on or off in the configuration.

PerfectGuard targets the following game versions and mods:

• ATLYSS 102025.a5
• Nessie's EasySettings v1.2.0 (optional dependency used for configuration)

Compatibility with other game versions and mods is not guaranteed, especially for updates with major changes.
