Field notes
The game separates an offensive terminal phase from a defensive SOC phase: actions taken during a contract later become alert entries mixed with routine events. The example shows an nmap scan producing port-scan and service-banner alerts, then asks the player to identify the related source IP. The homepage lists 103 contracts across four acts, supports Turkish and English, and describes an isolated lab with no external connections.
