The setting of this game is excellent, one of the most interesting I've run or played in.
The last bastion of humanity set upon and surrounded by the hordes of hell, which have been directly caused by the sins of man.
Its gritty, dark future with bags of ideas, full of juicy campaign ideas waiting to be exploited; Evil kultist bent on the dominance or destruction of mankind, using soul powered magic to bend reality to their ends.
The game system is ok, a little clunky but workable.
With some nice ideas for experience and motivation.
Where the book falls down is in its assembly/editing, its difficult to find anything- still its worth the effort as this is one over looked gem of a game.
