This book has extensive rules for technology in your game. Computers, Robots, Power Armor, A.I.s, you name it. It is perfect for anyone who wants to add high tech gizmos or strange devices to their game. I highly recommend this book to, not just playing Mutants and Masterminds, but anyone who plays D20 Modern or D20 Future games as well.<br><br><b>LIKED</b>: It was beautifully detailed, highly descriptive, and easy to intigrate into any D20 game.<br><br><b>DISLIKED</b>: I only got one download and I lost it. So I ended up paying for a book I no longer have thanks to computer error. I wish the site had account, back up.<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>
