Screen record your session
Alpha testers need to record both sessions. The recording is as valuable to us as your written feedback, because we can see exactly where things went wrong.
Use whatever screen recorder is easiest for you. Since you all have NVIDIA cards, the NVIDIA app (ShadowPlay) is the simplest option and costs almost no performance. OBS works too, and our guide covers both. Anything that records your screen and saves a file will work, and we can watch any common video format.
Screen recording setup guideAbout two minutes. Start recording before you launch Underwater, and leave it running for the whole session.
If you have any issues with the alpha build, you can join Lost Communications Discord server and ask for help.
Highly recommend to use a headset or headphones to experience the performance.
Hybrid In-Person & Online
If you successfully join the alpha build, your avatar will be projected into the immersive in-person performance, where you will meet An-Ting and Ian, as well as other digital and in-person audience in this underwater world. Enjoy!
