New location in SkidRow - Fight Club.
4 new characters (a trainer and 3 fighters).
Each fighter has their own storyline consisting of 3 quests.
After completing all storylines, you'll be able to participate in a tournament, facing off against 3 other fighters for a prize.
In each quest, you'll be fighting someone - but even if you lose, the quest will simply follow a slightly different path, possibly unlocking different scenes or causing you to miss others.

Each of the 3 fighters can train the player in one combat stat.
Various improvements have been made to most of the older game systems, along with several bug fixes.
