Only War
"...in the grim, dark future there is." -Yoda
The next entry in Fantasy Flight Games's Warhammer 40,000 Roleplay product line, in which players take the role of Imperial Guardsmen.
Therefore we can only assume that most of the book is based around the concepts of streamlined character creation, since Imperial Guard characters tend to not be around for long. Luckily, there are many of them, so you probably will end up playing a different character every session.
