This War of Mine, an indie game that explores the horrors of war from a civilian perspective, has released a free update that adds new locations to the game, a character editor, and more.

The two new locations are the Gas Station, one of the first places people looted while fleeing the city, and the Old Town, which lies in ruin like the rest of the war-torn city inspired by the Siege of Sarajevo during the Bosnian war.

The 1.3 update, which developer 11 Bit Studios says is the biggest the game received yet, also adds a new Scenario Editor that lets players write their own stories by picking which members can join the group, the length of the conflict, weather conditions, and more. Using the new Character Editor, players can also create entirely new civilians by changing their look, skills, and biographies. You can even put yourself in the game by uploading your own portrait picture.

This War of Mine received an 8/10 in GameSpot’s review for its gripping, emotional storytelling and character development. Earlier this month, 11 Bit Studios announced that so far it supported more than 350 Syrian children refugees through its DLC charity campaign, which launched last month to benefit the War Child organization.
