Answering how long it takes to beat Deathloop is as much an art as it is a science, because it's set in a time loop which could potentially keep on repeating forever, meaning you can technically extend the game length to however long you're prepared to continue going around for. Of course, there is an actual ending (several, in fact) to your time on Blackreef island, so it's more likely you want to know how long it will take to see the credits roll in Deathloop and you can feel that the job is done. Because the game is so open and there are many different avenues to explore, the answer to how long is Deathloop all depends on what you want to achieve and how you go about doing that. To help you reach an actual figure, we'll rough through some numbers so you have a basic idea of the time commitments required.
How long is Deathloop?
So the whole point of the game is finding a way to kill eight Deathloop Visionaries in one day, to break a time loop and escape the island. The game is very wide open, and lets you go pretty much anywhere and do anything, but it also has a laser focused objective tracking system. So how long Deathloop actually is depends on how you want to beat it.
It means if you want to finish Deathloop fast you can probably drill through it in 25-30 hours by sticking rigidly to objectives. However, that will be a fairly barebones playthough that won't show you half of what the island of Blackreef has to offer. You'll also miss out on some of the cooler power upgrades and Deathloop guns. A more in-depth playthrough, exploring side quests and mysteries, will easily take you up to 30-40 hours or more. For example, I'm currently in the 50-60+ hour area, having seen one possible ending and I'm still exploring the island trying to mop up side bits, mysteries, and open up some firmly locked doors by tracking down all of the Deathloop codes. So, there's a fairly big experience there, if you want to really dig in to it.
