11 Bit Studios’ harrowing side-scrolling survival game This War of Mine is ten years old today. And to mark the occasion, 11 Bit has unveiled Forget Celebrations, a new charity DLC being released as part of the game’s continuing “mission to shed light on the civilian cost of war”.

“Innocent lives are still being lost on battlefields, new conflicts are erupting, arms production escalates to feed war’s demand, and civilians and soldiers continue to face unimaginable brutality,” the studio writes in its announcement of Forget Celebrations. “With the world bleeding, we believe it is vital to keep pushing for change.”

In Forget Celebrations, 11 Bit once again returns to the fictional war-torn city of Pogoren, this time to tell the story of Katia, a seasoned war correspondent. “While struggling to write a book on the brutal realities of war,” the studio explains, “a missile attack devastates her home, forcing her into an even harsher fight for survival and the recovery of her gathered material.”

11 Bit hasn’t announced a release date or price for This War of Mine’s Forget Celebrations DLC as yet (and it’s so far only confirmed for Steam), but it says all studio proceeds will be donated to its charity partners – War Child, Amnesty International, Liberty Ukraine, and Indie Games Poland – in the “hopes of helping those affected by today’s ongoing wars”.
