U-CTF, short for Universal CTF, is a jeopardy-style competition set across the outer lanes: the transport corridors, relay routes, stations, and inhabited worlds that keep civilization connected. Teams are recruited as operator units to prove that the system is inherently flawed in every part. Their targets are vital pieces of infrastructure that serve, or once served, every citizen, from training stations and relays to maintenance networks and operational grids. Every challenge is a fault line in the machinery that holds the system together. Your task is to find it and break through it.
