The first campaign-focused downloadable content for the hyper-authentic shooter Arma 3 will touch down on October 31, developer Bohemia Interactive has revealed.

Dubbed "Survive," the free DLC introduces players to Ben Kerry, a NATO soldier on a peacekeeping mission put in the middle of a staged drawdown of US-led forces. With soldiers enforcing a multi-year cease-fire in the game's fictitious Mediterranean setting, a hostile opposing force emerges to ignite the sensitive region.

"Of course, it's not just about our own story, but another opportunity to provide yet more building blocks for the platform – new weapons, animations, 3D objects, scripted modules – each designed to grant content creators even greater freedom to create and share their own content," Arma 3 Creative Director Jay Crowe wrote in a post revealing the content's release date.

Crowe adds that future content will continue to expand Arma 3's impressive and extremely "moddable" sandbox with "additions such as new vehicles."

Arma 3 is available now for PC.
