This War of Mine is a dark survival game where you control a group of civilians trying to stay alive in a besieged city.

Your task is simple: survive.

The pace of the game is imposed by the day and night cycle. During the day snipers outside stop you from leaving your refuge, so you need to focus on maintaining your hideout: crafting, trading and taking care of survivors. At night, take one of your civilians on a mission to scavenge through a set of unique locations for items that will help you stay alive.

Make life-and-death decisions driven by your conscience. Try to protect everybody from your shelter or sacrifice some of them to endure the hardships. During war, there are no good or bad decisions; there is only survival. The sooner you realize that, the better.

With today's 1.3 update -- the biggest one to date -- the team has added a scenario editor, as well as a character editor, along with additional content in the form of two new locations and two new music tracks.

This War of Mine has always been a somewhat difficult game to play -- not just because it's challenging (it is), but because of the life-and-death decisions you have to make, along with the personal relationships that develop between characters, as conveyed via their in-game journals. Further, it's worth noting that the characters already in the game were based on people close to the development team, ensuring that the experience was exceedingly personal for the people at 11 bit.

Will players choose to put their friends and family into the game, further increasing the emotional attachment to characters? I'm very interested in seeing where user-generated content goes.
