Main challenge
The objective of this project was to experiment with object interactions and a simple Minecraft-style inventory system in Unreal Engine 5.
Having recently finished and greatly enjoyed the game Skin Deep, I wanted to take advantage of this project to also create a narrative experience parodying the classic tropes of heist and spy movies.
 The challenge was also to make the experience more polished by adding SFX and a real soundscape to each level.


Design process
Once we had the concept in mind, we started by listing the tropes of the genre that we liked: an expert is called in to do one last job, auctions, rooms full of lasers, etc. I was able to write the story, the voice lines, and other elements necessary for understanding it.

Then I wrote the sequence for each level so that Antoine, the level designer, could start working. 

Next, I went through each level to create the blueprints for the objects needed for the player to progress.

Finally, I found, mixed, and integrated the music, sound effects, and voice lines for each level.


Results
The end result is a game that tells a story across three levels: Introduction in the apartment, infiltration of the mansion, and breaking into the safe. Three characters are introduced, and we learn about their past relationships and where they are today. A final plot twist keeps us on the edge of our seats. And all this in a 10-minute experience!



My contribution
  • Initial idea
  • Writing the story, voice lines, and integration
  • Mixing and integrating music and SFX
  • Scripting (interactive objects, animations, transitions)


What I learned
  • How to integrate spatialized audio into Unreal Engine 5,
  • Scope small,
  • How to fragment a narrative to make it understandable to the player bit by bit.
