A new custom campaign for Portal 2 was release just the other day. Designed for Danger is a collection of eight new maps that offers up over an hour of new puzzles.
You can install the campaign either through the Steam Workshop (recommended) or from this download mirror.
In the campaign, you assume the role of Chell during an early part of Portal 2. This time however, things turn out differently. The actions of a rogue force will set you on a new path through Aperture Laboratories.
Watch your step and prepare for adventure!
