402 must be my favorite Breachworld character. I find him to be a fascinating twist on the standard trope of the remorseless killer. He can work as a PC due to how he is a dynamic character whose goal is learning and upgrading his software continuously. He's best suited, however, as an NPC villain.
In game balance, 402 is a little highly specialized for combat. As a PC, he might be a tad overpowered compared to other starting PCs. His sniper rifle is straight out of the standard equipment list, but at 7D damage, it's the most powerful standard firearm in the Equipment section. To keep 402 from dominating combat easily, the GM needs simply to track his ammo usage, because bullets are valuable and in limited supply in Breachworld.
The PDF is 9 pages long, not including two pages of contract legalese at the end. It's crisp and easy to read. The text is copyable which is important to some of us. Included is an extensive description of the character and his background, 4 different versions of his character sheet representing the same character at four stages of experience (the only changes being stats and one skill specialization that he picks up over time), and four brief adventure hooks. I really like how Jason provides the four character sheets, going out of his way to do the book keeping for us.
If there is any weakness in this folio, I would point towards the adventure hooks. They aren't bad. They are just meh. Only the last hook, "Fritzing Out," uses the character in a way which is not obvious.
