One of my responsibilities at FireSprite was to upgrade the companion app for The Persistence. The Persistence is a VR horror title for consoles and PC with a couch co-op element. The companion app is a mobile app that can communicate with the main game, for example you can click on a door in the app and it will open or close in the game - you can choose to help or hinder whoever's playing next to you. The task of upgrading the app involved learning to use Android Debugger, Android Studio and the online publishing tool that Google provides. The majority of the version upgrade was checking parity with the previous version, fixing missing text, and adding missing translations. I was the sole developer on this task.
