Incursion: Halls of the Goblin King is a freeware roguelike game based on the mechanics of the d20 system, available under the Open Game License by Wizards of the Coast. The game boasts 9 races, 10 classes, 45 skills, and 18 choices of god (including no god), each requiring totally different strategies to be played effectively.
Playability and Completeness
The game is unfinished, but complete enough to have an active playing community. It is currently maintained by someone other than its creator. Its source code has been released, so it is possible for other build upon the existing framework.
According to the its creator, Incursion: Halls of the Goblin King was "a promo game for the upcoming roguelike epic Incursion: Return of the Forsaken", which would have featured overland map, multiple dungeons, towns, more prestige classes and other features. Return of the Forsaken was slated in the best case scenario for a release in the last quarter of 2011.
A detailed tech doc about the game is provided here. It could prove useful in roguelike development.
On 2013-04-14, its creator posted a proclamation that development on Incursion was finished--having moved on to other interests, he no longer had time or interest in maintaining the project. On 2014-03-16, after offers to maintain the codebase and fix the bugs, he posted to the Incursion Google group announcing the release of the source code for the last couple of released versions.
The Source Code
The official released source code can easily built by following the instructions given in the release post. Unfortunately, it is based on an old, unsupported version of Allegro, which has been a source of many show-stopper bugs.
