"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.
Based on player feedback, I improved the readability of the first screen, where you start creating your character. Some captions were changed and the next and load buttons are now separate from the reroll button.
