Like most Roblox games, Brookhaven has codes that players can redeem for free content. However, this is not the usual content that they would expect elsewhere in Roblox.

Here are all the codes for Project XL in March 2021 - these include plenty of Mastery Experience and a selection of boosters.

Roblox Brookhaven doesn't have promotional codes like other Roblox games. Instead, it provides players with Music Codes to enjoy some of the most popular songs available today.
