Days is a compilation of all "Days" related mappacks (Day 13, Day 14, Day 15) into 1 mod. All mappacks by Chris Fox. Story (taken from Readme): "You're Gordon Freeman (surprise!). You got captured and the combine imprisoned you in a re-education centre. They have been putting you through reality simulations for the past few weeks. At first these were relatively benign. But on Day 13 things hotted up when you were placed into a violent combat trial, and on Day 14, your wits were tested with surreal puzzles. What will happen, on Day 15? Is there any hope of escape?"
