Shift 233

You are at Station 4's microseismic monitoring post, just starting out as a new employee on Shift 233. The only thing you hear for most of the shift is static noise, computer servers running, and the occasional sound echoing throughout the station. Just when you think it's going to be a peaceful shift, you hear something strange.

As an operator, you will:

• Adjust bearing and range dials to find incoming event signals

• Play back each event's waveform

• Log each event as real or dismiss it as noise

• Keep the array lights aligned

• Read through logs of a previous operator and chat with a colleague named Sam J.

The entire experience is under an hour. You will be left with more questions than answers by the end as to what lies deep below.
