Deathloop is a time-loop first-person shooter where two rival assassins, Colt and Julianna, are trapped on the island of Blackreef and must eliminate eight targets before the loop resets. Players can explore the open-world island, gather abilities, and experiment with multiple strategies to break the cycle. The Deluxe Edition adds exclusive content: three unique weapons (the "Rich Selection" Tribunal, .44 Karat Four-Pounder, and MG-1 "Pepper Mill"), two character skins (Party-Crasher Colt and Sniper Julianna), and two sigils that grant permanent buffs, offering extra customization and firepower.
