This talk will dive into the Modular Weapon Audio System designed for Borderlands 3. The weapons in Borderlands 3 are built from individual assets that allow for the gun to be randomly assembled from a set of parts. The Weapon Audio System builds on this approach and uses game parameters and granular audio assets associated with each weapon part to produce "a bazillion" unique weapon sounds.


Designing a system that uses modular pieces has distinct advantages, most importantly variety. However, it comes with great cost as well. Attendees will gain insight into the cost and benefits of this particular system and learn some of the ways in which we overcame our most significant challenges.

Intended Audience

The intended audience for this lecture is open for anyone interested in how granular weapon audio is created and implemented in to a very robust modular weapon system to provided "bazillions" of variety.
