This project aims to create an innovative and tense cooperative experience for players by utilising custom hardware.
The application runs on an asymmetric two-input system: one player operates within the Unity game world created for the project, while the other operates a custom physical hardware controller to communicate and defuse the bomb.
Technical report on the project can be found here (May require downloading due to file size).
Watch the technical video and trailer here.
Project Setup
To fully experience this project, a physical 'hardware bomb' controller is required.
Prerequisites
- Microcontroller: Teensy 4.1
- IDE: Visual Studio Code with the PlatformIO extension
- Game Engine: Unity 6.3 LTS
1. Hardware Setup
- Clone this git repository to your local machine.
- Open the
Hardware/ControllerV0.1folder in Visual Studio Code. - Ensure the PlatformIO extension is installed and active.
- Plug the Teensy 4.1 microcontroller into your PC via USB.
- Press the PlatformIO Upload button (the right-pointing arrow in the bottom status bar) and wait for the upload to finish.
2. Software (Unity) Setup
- Open the
Team_Projectfolder in the Unity Editor and import any required packages. - Build the project using Build Profiles, selecting your target operating system.
- Connect the flashed hardware controller to any open serial USB port on your device.
- Launch the built executable.
- Enjoy and try not to explode!
Note: If you do not have the required custom hardware, the level will still open and assign a Mock API. However, the game will not be playable, as the physical interactions required to navigate and access the game states will be absent.

Questions
How big is the Fishing Game Circuit PCB?
It measures 86.4 × 96.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fishing Game Circuit use?
27 parts, built around the SN74HC595N and DTS-62N-V. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Fishing Game Circuit KiCad files?
From the felixUOB/Two_Defuse_Or_Not_Two_Defuse repository on GitHub, at the commit this page was made from: the board is Hardware/Circuit_Designs/Fishing-Game-Circuit/Fishing-Game-Circuit.kicad_pcb and its schematic Hardware/Circuit_Designs/Buttons-Circuit/Buttons-Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fishing Game Circuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask felixUOB before reusing the design.
