Codebreakers

When a power surge sends the Core Four's tram into uncharted territory and the arcade into a blackout, the gang finds themselves trapped with no way to get back to Central. They come to discover, however, that getting home is the least of their worries. There's a dark secret lurking within the walls of Litwak's arcade... a secret that has spent the past six years just waiting for the right opportunity to make itself known.
