Radical Approach has released the second edition of Trauma, a plug-and-play set of rules that can be added to any roleplaying game if you want to add a whole new level of hurt to your game.
Written by Claus Bornich, Trauma provides rules, descriptions and medical details for all kinds of injuries based on medical research and literature, adapted for roleplaying games.
The 187 page book has a chapter for each of the five body parts (head, chest, abdomen, arms and legs) to describe the risks, symptoms of injuries and their treatments (whether through traditional means, surgery or magic) for different roleplaying genres and time periods.
It also comes with tables to determine the location, severity and trauma suffered by the characters at the end of combat, so that it keeps the game fast-paced and does not interfere with the game mechanics that it is being adapted for.
Although originally written for the DICE system in mind but the rules are neutral enough to be adapted for other system. You can find a free PDF guide here on how to use the book for the D20, GURPS, The Riddle of Steel and the Storytelling systems.
You can also see a preview of the book here.
Trauma is available as a PDF for $9.00 or a softcover for $22.44 (reduced from $51.19) at RPGNow and DriveThru RPG.
A hardcover edition is available at the Radical Approach store for £18 (not including shipping).
Any order of the print editions (both soft and hardcovers) will be given the PDF version for free.
