Horizon Zero Dawn Conversations Are Generated By ‘Rule-Based System’, Insipired By CDPR and BioWare

Horizon Zero Dawn is the first open world action RPG from Guerrilla Games. It has been finally released to critical acclaim and the game also appears to be one of the best looking game to be released this year.

At their GDC 2017 presentation on the creation of Tools Pipeline for Horizon Zero Dawn, Guerrilla Games broke down the various system and tools that were used to develop Horizon Zero Dawn. You can read more about the evolution of DECIMA engine from here, but the interesting tidbit in the game was about the conversation system.

We learn that the conversations in Horizon Zero Dawn can also be auto-generated and this is decided by a ‘rule-based system’ that they specifically developed for the game. They showed an example of such auto-generated conversation that used RoboVoice and Lip Sync animations from mock-up content to create a conversation.

This is one of the many features that Guerrilla Games developed in order to create Horizon Zero Dawn. The game also used GPU-based procedural placement for Flora and Fauna among other things.

Horizon Zero Dawn was released on February 28th exclusively for the PS4. It was developed by Guerrilla Games on their newly released DECIMA game engine. This engine is also being used by Hideo Kojima for his upcoming Death Stranding.
