"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.
This is the new character creation screen. Everything now in a single readable screen, no more juggling "Next". Also, the game now suggests the best class and background for you.
There's a kink or two to be ironed out, but they don't detract from playability.
