This page details development materials of Dungeon Siege.
On January 2nd of 2023, the source code of Dungeon Siege was leaked. This build appears to have had been compiled in 2003, the same year as Legends of Aranna, but does not seem to contain any of LoA's code.
Unused Mechanics#
Loot Filter#
Most loot based Isometric ARPGs include a method of clearing up the loot you can see or click by implementing loot filters. Within the recently leaked files (more specifically ui_options.cpp), there are several lines at the bottom that detail a filter that was never implemented.
One theory the community has is that this build may have been an inbetween of Dungeon Siege 1 and Dungeon Siege 2.
