"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 case you are wondering 'what am I doing here again', the game now uses a main quest to remind you. Press Control-Q to see the quest list.
Looking good man, I'm glad to see progress is still being made
Thanks, your comment means a lot to me! I had a couple months break due to job, but I'm back and I think the next beta will come before the Paralympics start (that's 7th Sep for those less sport-inclined)
