Rebellion has revealed its post-launch plans for the co-op supernatural shooter Strange Brigade, which will include a three-part "mini-campaign" available in a season pass and free monthly updates that the studio promised will "escalate the escapades."

Strange Brigade follows four adventurers, each with unique weapons and abilities, as they roam through an pulp fiction-styled 1930s Egypt and battle the forces of the undead Witch Queen Seteki. Shooting stuff is obviously job number one, but Rebellion said it will also feature environmental traps, secrets, puzzles to solve, and "ancient contraptions that need awakening."
