The system exclusive uses the Playdate's crank to control the train's speed, and Bridges has recently revealed that he's aiming for even more authenticity by including the vocal talents of Tokyo-based Australian singer and voice actress Donna Burke.
Burke has worked in the realm of video games and anime for some time and became involved with the Metal Gear franchise with Peace Walker, for which she supplied the vocals to the song Heavens Divide.
She then voiced the iDroid robot in both Metal Gear Solid V: Ground Zeroes and Metal Gear Solid V: The Phantom Pain, as well as supplying vocals to the song Sins of the Father. She has also lent her voice to games such as Boktai, Lunar Knights, Silent Hill 2 and Silent Hill 3.
In addition to this, she's also the voice of the Tokaido Shinkansen "bullet train" – which makes her inclusion in Zero Zero: Perfect Stop even more fitting.
The game is apparently close to release. Keep your eyes on its official site for more info.
