How AI is used
Our team utilizes AI in a variety of ways to improve the quality of our game. Here are a few examples of how our team incorporates AI into our development process: 1. We use AI to translate dialogue, subtitles, and (more infrequently) music into a variety of different languages spoken by players of our game. This allows more players from different regions to enjoy playing Operation: Harsh Doorstop in their own language, and helps us reach more players throughout the world. 2. We utilize machine learning to help train our NPC bots, giving non-player characters more realistic and adaptive behavior on the battlefield. 3. We utilize AI to assist with finding bugs and other issues in the game, which our developers can then diagnose and fix. We currently work with the RevoltGPT team to help us incorporate AI into our development workflows. If you're interested in learning more, you can visit their website at https://rvt.dev
