SecretLab stress test

Emulates SCP: Secret Laboratory server traffic against your own game instance to verify it stays joinable under attack-grade packet load.

How it works

This method sends a high rate of packets shaped to resemble legitimate SCP: Secret Laboratory client and server exchanges, aimed at the game's listening port. Because the traffic mimics real session chatter rather than random junk, it pressures the connection tracking, session handling, and per-player processing on the game server and any protective proxy in front of it. Use it to confirm that real players can still connect and stay in-session while the box absorbs the load.
