The information on Altforf isn't as detailed as that given for Middenheim in the previous installment. Part of this is purely down to the sheer size of Altdorf; it's a huge sprawling city, it would be impractical to go into the level of depth that was provided for Middenheim. Instead we are given detailed descriptions of specific places of interest in the city and a general idea of how to evoke Altdorf. All of this information is very useful and comes with plenty of ideas for encounters and adventure hooks.

After the fairly straightforward plot-line of Ashes Of Middenheim I was somewhat suprised by how convoluted the plot of Spires Of Altdorf appeared on first reading. There's three main plot lines going on at the same time, all of which have the potential to overlap and intermingle with each other. Two of these plot lines are failry easy to get your hear around - one involves a certain character's attempts at getting revenge on the characters, the other involves a shady character attempting to manipulate the PCs for his own dark ends. The third plot line (the main one really) involves a lot of investigation and has a large cast of characters which the PCs will have to deal with.

The adventure is fairly non-linear (far more so than Ashes Of Middenheim) and will require the GM to put some work into it before running the game. The PCs are free to do things at their own pace, in whichever order they desire ( and as PCs are wont to do, you can guarantee that they'll go down some routes that haven't been anticipated by the book which will require some inventiveness on the part of the GM).

This is a much tougher adventure to run than Ashes Of Middenheim, but then that's the price you pay for a more involved and organic story line. It's not easy to run but it is, in my opinion, another good addition to the Paths Of The Damned Campaign.
