Kritika Online has been updated with v450: Halloween that brings the Haunted Room on board as well as a number of adjustments to drop rates, side-story missions and item bindings. Most of these changes have been made as a result of player feedback.
Players can enter the Haunted Room four times a day and work to earn "tons of ghastly gear including cosmetics, a pet and a title".
Be sure to head to the Kritika Online site to check up on more of the patch note details.
