Bug-out Shelter #6 – Misleading Transmission

Mission

The verdict is clear: the raiders are closing in — and they now know that a fully functional shelter is hidden somewhere nearby. Promèthes.

You have only one option left: mislead them.

Maxime suggests a risky maneuver — deliberately broadcasting false data using signal fragments recovered from the military base. The goal is to generate an artificial echo: a radio or energy signature convincing enough to make them believe the shelter is located somewhere else.

The decoy must be credible. The coordinates, signal strength, emission frequency… everything must look authentic, without exposing Promèthes. One miscalculation, and the shelter’s cover is blown.

Rules

We are still in a two-dimensional space, x and y, expressed in meters.

You have at your disposal the x and y coordinates of three sensitive zones of the Promèthes shelter: the shelter entrance, a ventilation tunnel, and a waste evacuation tunnel.
Each zone is represented in the format x,y in the variables z1, z2, and z3.

You also have encrypted coordinates of raider squads located not far from the shelter.
To push them away, you must send them fake coordinates, which will move them 100 meters away from the closest sensitive zone (100 meters on the X axis and 100 meters on the Y axis, not 100 meters diagonally).

Depending on where the squad is located, you must push it in the opposite direction from the zone’s position (to move it as far away as possible).
You do not need to take into account whether the squad might be redirected toward another sensitive zone.

For each coordinate, you must:

• Decrypt the coordinates
• Determine the coordinates to send in order to move the squad away
• Encrypt the coordinates

You must return all the encrypted coordinates, separated by dashes.
