Borderlands 3 Anniversary Celebration Kicks Off with Bonus Legendary Boss Loot

All this month, Borderlands 3 players will be getting extra loot for the series’ 10-year anniversary, starting with increased Legendary drops from bosses this week.

From Oct. 1 to Nov. 4, Borderlands 3 players will have the chance to earn extra loot for all kinds of different activities as the series celebrates its 10th anniversary. Each week will have a different theme, which dictates the type of bonus loot dropping and how players can earn it.

Now through Oct. 8 is Boss Week, which gives an increased chance for Borderlands 3’s bosses to drop a unique piece of Legendary quality loot when they’re defeated. Some bosses affected by Boss Week have an increased chance to drop Legendary class mods. There are also some excellent weapons on the list, including the Ten Gallon submachine gun, which turns spent ammo magazines into walking assault drones when you reload.

The full list of events for the Borderlands anniversary month, again courtesy of Gearbox:

The official anniversary of the original Borderlands’ release date is Oct. 20. We may see a surprise event to commemorate the date, but nothing has been announced to that effect yet. Gearbox did say it’s “saving some surprises for later” during its anniversary month. It should have some exciting plans not covered by the event calendar it released today.
