If you haven't played the critically acclaimed game This War of Mine yet, now might be the perfect time to try it. Right now, you can buy the title at a massive 80% off, but keep in mind that the sale ends in 1 day from the time of writing.
This War of Mine is a war-themed game with a unique twist – instead of slaughtering foes on the battlefield as a solder, you are put in a situation where you have to survive the horrors of a civil war with a group of civilians. Yeah, it's not really a good time, as the game pulls at your heartstrings with every new survivor you find... or every single one that you lose.
It's a well put-together masterpiece of survival/base management/visual storytelling and has been lauded by both players and critics. It also has an expansion with extra levels, which will set you back another $2.59.
