...To Be Left Alone

...To Be Left Alone is a challenge in Risk of Rain 2. It is completed by finishing the Void Fields, a Hidden Realm found by activating the Null Portal in the Bazaar Between Time.

Under the Bazaar in the Bazaar Between Time there is a hidden cave that leads to a purple portal. This portal leads to the Void Fields. Beating the nine challenge cells in the Void Fields will unlock Acrid.

Trivia
The name of this challenge refers to the ending quote from the original Risk of Rain when completing the game as Acrid. The entire quote is "...and so it left, with a new hunger: to be left alone."
