"A fantasy d20-themed dungeon crawler", to quote DarkGod's comment. Inspired by Incursion by Julian Mensch. Made available under Open Game License. This is a non-profit fan project. No money is made. There are currently only two people working on the mod. However, we have released several beta versions so far.
In the process of migrating skills to external data lists, the skill select screen was improved. The ugly underscore in two word skill names is no more and everything is procedurally generated from the data, no more fat local list specific to this screen only.
