The Sewers

Complete the Alley to unlock the Sewers, one of two branching paths in Act 1. The Sewers is a dank, waterlogged area that eventually leads to the Caves. It features new enemy types and environmental hazards compared to the Alley. Choosing the Sewers path means you will need to complete the Junkyard/Boneyard branch separately later, since both paths must be cleared to reach Act 2.
