Hidden Invasion Secret Files #2: Area-51 Technical Briefing is unique among game products - it purports to be the manual for new employees at the Groom Lake Facility, commonly known as "Area 51". As such, it contains no system specific material, making it equally useful for Hidden Invasion as well as any other modern conspiracy roleplaying game. Featuring the artwork of Philip Reed (Spider Bite Games, Ronin Arts, Steve Jackson Games), this book is a stand-out for artistic achievement! This book is over 100 pages of just plain cool stuff!
