From GameWatcher: “Although it retains its immersive sim roots, Deathloop is a different beast in developer Arkane Studios’ portfolio thanks to how it frames its action within the boundaries of a repeating time loop through which players gradually progress using the knowledge earned from each death. On top of that, it also has a more freeform structure.
Its approach to gameplay sees it shed the traditional missions of titles like Dishonored, which often had entire levels built around the tasks Corvo and Emily had to complete. In Deathloop, players will be able to choose how and when they tackle main and side objectives, the developer pointed out in a recent Discord AMA session.”
