Today, 2K and Gearbox Software announced Hallowed Concepts, the fourth expansion coming to Risk of Rain 2. Check out the teaser trailer here.

In this expansion, the lessons of darkness and death, once contained to rumour and hearsay, are getting louder and harder to ignore. Hallowed Concepts takes players deeper into the cult-like world of N’Kuhana. Survivors will fight through haunting new regions of Petrichor V, face horrific new enemies, and uncover powers never before possible in Risk of Rain 2.

Hallowed Concepts offers powerful curses to overcome, deadly trials to face, and new stages to explore, including the fetid depths of the returning Damp Caverns, the villages of the Tenebrous Quagmire, and the sacred ground of The Lurid Basilica. Players can explore this new content as two new playable Survivors coming as part of Hallowed Concepts.
