Aegrus is the new continent in Sir Hammerlock's Big Game Hunt DLC in Borderlands 2
You arrive there to accompany Sir Hammerlock on a fun filled weekend hunting trip.
Aegrus is a continent that time left behind. Nobody comes here and you will not find many NPCs or settlements. What you will find here, is a lot of wildlife and danger. This area has caught the attention of Sir Hammerlock who wants his friends (meaning you) to join him on a hunting adventure.
Aegrus is a jungle-like setting, with many swamps and mountains.
In Aegrus you will find indigenous creatures unique to this area, as well as savage human enemies. Most of these inhabitants want to eat you, or kill you, or both, so don't try to reason with them. The fact that you are here on a hunting expedition doesn't help your cause much either.
