"In 2031, NeoCorp's internal routing network was the most secure in the world — or so they claimed."

You've infiltrated their network as an unprivileged contractor node. Somewhere deep inside their proprietary routing mesh sits Node 3 — an isolated server holding classified data their security team thought was unreachable.

Their custom routing protocol, RTUN, was designed in-house. The spec was never made public. The source code was never audited. And the engineer who wrote it left the company in a hurry.

You have one entry point: Node 1. You have one tool: a raw TCP socket. You have one question:

What did that engineer leave behind?

The router is listening. It will talk to anyone. But it won't give up its secrets easily.
