It's different: ARC Raiders creator commented on the AI usage warning that appeared on the Steam page

Various technologies were used to create the extraction shooter.

The extraction shooter ARC Raiders from Embark Studios was recently launched. Players on the Steam page noticed a warning that AI was used in the work:

In the development process, we may use procedural and AI-based tools to create content. In all such cases, the final product reflects the creativity and self-expression of our development team.

In a conversation with PCGamesN, design director Virgil Watkins stated that they do not use generative AI and there is actually no generative content in the game:

There is no generative AI used in ARC Raiders at all. We use something called machine learning, or reinforcement learning, and it's responsible for the movement of our big multi-legged drones, but there's no generative content there

ARC Raiders also has text-to-speech technology to create new lines:

[this is] the same as in The Finals: we use the same text-to-voice model. That is, we contract voice actors - it's part of their contract that we use AI for this purpose, and it allows us to do, for example, our ping system [signals], which can pronounce every item name, every location name, and direction on the compass. That's how we can achieve this without human assistance every time we create a new item for the game
