SewerJacks is a Win32 Roguelike written in seven days as part of the 7DRL challenge in March 2007 .
A game inspired by Jervas Johnson's tabletop fantasy football game, Blood Bowl(TM) and William King's Troll Slayer novels.
You play the role of a Sewer Jack, whose job it is to clean the sewers of all nasty inhabitants and ultimately kill the end boss to win the game. You can team up with fellow sewerjacks found lurking in the depths.
The game is an attempt to convert the rules of Blood Bowl to a roguelike setting. SewerJacks uses races, skills and the combat system based on Blood Bowl. [Official site]
