Catalyst Game Labs posted up their 3rd preview .pdf of Shadowrun 5th edition up online.
From the preview:
The third free preview of Shadowrun, Fifth Edition is now available! To review, the first preview had fiction and flavor text to help convey the look and feel of the game, while the second preview contained the Game Concepts chapter, giving the basic structure of the game. The third preview gets a little flavor and a little mechanics–it has the short story (written by Patrick Goodman, author of Another Rainy Night) leading into the Character Creation chapter, along with the first few pages of that chapter, giving you a taste of how character creation works in Fifth Edition.
