Using the numerous scanner made available by the Banshee's sensor array, Rex started looking for some kind of entrance, even a hidden one. Sadly he was quickly disappointed. A playground surrounded by trees were all that to be seen around. There was no building that could hide some kind of secret entrance. Around the Spielplatz, the hill side were covered with remains of typical, small suburbs housing. Sadly, the scans provided by Racer clearly show that most of those houses did not have a basement. And even if some, a bit farther away, seemed to have some basement, none appears to be either connecting to a forgotten bunker - neither reusing its infrastructure.
At this point, Waywalker took over the control and started working its "own" magic. Adding filter, compensating for noise, boosting signal, rewiring external sensor to correlate data... It was impressive. Rex knowledge of technologies was sufficient to realize that the rigger was doing some pretty high end stuff. Here and there, Racer's icon - not surprisingly looking like a racing car, jumped in to provide some extra help or suggest some tuning.
Rex, as always shaped as dog, was sitting in the middle of ball of flying AROs and screen being passed around between the decker and their AI ally. The all things looked like a technical, AR version of a famous movie from Horizon, where a mice called Mickey was learning magic... After a little while, numerous new information starting popping into the matrix, and a deep scan of the belly of the hill starts appearing. And, of course, as it often seemed to be the case on this run, this was not good news.
The bunker was still there and clearly in one piece. Its thick walls appears to have not been breached, which means no digging out dirt to get inside it. However, no breach also meant absolutely no chance to scan its inside. To make matter worse, the top part of the bunker, closest to the surface, was still, around 20 meter deep under the surface. Clearly, the all building had been buried rubble - a bit like they did in Berlin after the WW2, as Rex recalled, and there was simply no (human) way to get to the building.
However, the scan also revealed that the hill has been suffering from the tired mountain syndrome for a while[1]. The nearby remains of Metz have been blasted to hell during the first rounds of Rad Wars back in '71 and numerous explosion, both above and below ground, had started to broke the mountain from inside. Thanks to the advanced analysis of Waywalker, the runners could now see that some cracks formed very narrow tunnels that appeared to reach the top of the bunker.
Something as small as a dog or Waywalker's Nestor unit, might be able to crawl up to there. It would be no easy feat and then they would still be the issue of being able to break into the century old bunker...
