Backrooms Anomaly is made by a tiny team, and this Supporter Pack is just our way of saying thanks if the game stuck with you. It is a tip jar, nothing more: buying it does not change gameplay, difficulty, anomalies, or endings. In return, you can recolor the Hazmat Warden who patrols the corridor. There are gold, blue, red and green versions, and you switch between them from the main menu. That is everything in the pack. We have not cut anything from the base game to sell it here, so if you would rather not spend the extra, you are not missing anything. Thanks for supporting independent horror.
