There are some valuable rewards to collect by opening the Brighthoof Secret Catacombs in Tiny Tina's Wonderlands, including a Doom Easter Egg weapon, but there are two side quests that must be completed to open the gate. The Secret Catacombs are located through the gate near the Wibblesern Well in Brighthoof. To open the gate, players will need to complete the "Lyre and Brimstone" and "Inner Daemons" side quests in Tiny Tina's Wonderlands.
The Secret Catacombs gate will be opened during the "Inner Daemons" side quest, but "Lyre and Brimstone" needs to be completed first to unlock it. The first side quest has players helping with a Battle of the Bands competition in the forest, and the second mission involves opening the gate by performing sins around the city. The recommended level to start the "Lyre and Brimstone" side quest is 15, but lower level players in Tiny Tina's Wonderlands can still complete the mission in multiplayer.

Completing "Lyre and Brimstone" will earn players $9,195 and 5,688 experience as well as the Metal Lute of Myth, a rare melee weapon. Only 565 experience points will be earned for completing the "Inner Daemons" side quest, but players will earn $10,299 and unlock a weapon that directly references a Doom gun. The Heckwader of the Hurricane is a rare SMG that deals fire damage, and it has 15% increased reload speed and 21% increased fire rate. Completing both side quests will earn players a decent amount of money and two new weapons, but each mission has several steps to get through.
The "Lyre and Brimstone" side quest can be picked up from the Bounty Board or started from the quest location in Tiny Tina's Wonderlands's The Horns area
