This level messed with my head as an 11 year old. The concept of an impossibly large fortress riddled with tunnels and arcane technology. The lost world is very interesting.
This theme is so 80s/early 90s inspired, it's almost a clichè.
And it still manages to work for it's intended purpose.
The Campainer's Fortress gives you an imposing trek through a highly advanced technological bastion, and Darren gave us a theme for it that perfectly embodies the level:
* Bleak. Imposing. Hopelessness and despair manifest.*
It's perfect for what it is: A lemotif for the base of operations the most dangerous entity in all of Galyanna, The Lost Land: A despotic android/cyborg hellbent on universal domination.
