It appears that a group of indie studios have decided to join forces for a mysterious collaboration. The so-called Triple-i Initiative brings together studios behind games like Vampire Survivors, Darkest Dungeon, Slay the Spire, and more.

More than 500k players have already purchased Deep Rock Galactic: Survivor. It took the new auto shooter just one week to reach this milestone.

Deep Rock Galactic: Survivor, an auto shooter based on the world of the original co-op FPS by Ghost Ship Games, has proven to be a surprise hit. And it looks like even the studio itself didn’t expect such a strong player interest.

Ghost Ship Games has shared an annual recap for Deep Rock Galactic. The studio disclosed its hit co-op title’s sales and other metrics such as DAU and MAU.
