This project is still in progress. I have only been able to find very little information about their interior setup. It currently has a console with 3 radios, one of them being an optional extra, as that's what they appear to use based on a video that showed a glimpse of the interior. I'm unsure about what siren controller to use, if anybody knows what's most likely used IRL or if anybody has any suggestions for a fictional setup, please post here.
