if i remember the latest update correctly, atleast 1 ending is complete. and the dev is working on the rest.
the game is playable, but make a save before you near the end, because their changing and updating the final bit of the game. which breaks your save if your around that point.
its a game that requires multiple playthroughs, and multiple tries with different classes. so bear tat in mind if you want to get the most out of the game.
also be warned, its pretty brutal, you really can only take on 2 guys at most. there are many situations where you want to flat out AVOID combat, you really arent a superhero.
Also this isnt one of those "even if my skill isnt high enough, i can still try it without consequence" games, if for say, your disguise skill isnt high enough, then you really shouldnt attempt to put on a disguise because people will try to kill you when you fail.
but its definitely fun , IMHO one of the few RPGs that really gives consequences to your actions and decisions. Hell, even taking the time to travel between cities will move time forward and alter/change events in the game.
