OPUS is an immersive point-and-click horror adventure game that transforms your Apple devices into a seamless, multisensory escape room. Designed for iPhone, Apple TV, and Apple Watch, OPUS leverages motion tracking, heart rate monitoring, and local networking to deliver a cross-device gaming experience.
🏆 Winner of the "Alfredo Petrosino - Best App Award" for innovative use of Apple hardware.
You wake up trapped in an old friend's home, now twisted by the aftermath of his alchemical experiments. Your only chance to survive, and save him, is to explore, stay calm, and complete the mysterious Opus Magna ritual.
Using your iPhone as a flashlight and input device, your movements sync in real time with the TV, while your Apple Watch tracks your heart rate, amplifying the tension as danger draws near.
- 🔦 Point your phone to explore
- 💓 Control your fear
- 🧩 Solve puzzles and follow clues
Built entirely in Swift, OPUS takes full advantage of Apple's frameworks:
| Framework | Purpose |
|---|---|
SpriteKit |
2D game engine for rendering and animation |
MultipeerConnectivity |
Real-time local device communication |
CoreMotion |
Phone orientation and motion tracking |
CoreHaptics |
Tactile feedback during gameplay |
HealthKit |
Live heart rate monitoring from Apple Watch |
The project includes multiple targets inside opus.xcworkspace:
OpusGame/OpusTV: Main game engine running on any iOS device (iPad suggested) or Apple TVOpusIOS: Companion input controller app with motion handlingOpusWatch: Optional Apple Watch extension for biometric input
Setup:
- Minimum setup: 1 iOS device + Apple TV or 2 iOS devices
- Full setup: iPhone + Apple TV + Apple Watch
