How long is The Callisto Protocol: Dani, a young female member of the Outer Way that's also trying to escape Black Iron prison

Just how long is The Callisto Protocol? Striking Distance Studio’s story-driven sci-fi horror is relentless, and you can expect setbacks at every turn as you escape Black Iron prison. As you stumble from one bloody confrontation to another in the game’s many chapters, you may start to wonder, ‘how long is The Callisto Protocol, anyway?’

The Callisto Protocol spans eight chapters, taking roughly 12-14 hours to complete. If you’re adamant about searching every dark corner on Callisto, you might find it takes you a tad longer – especially if you’re dead-set on uncovering the mystery of The Callisto Protocol Kallipolis while you’re at it. The Callisto Protocol is very linear, so subsequent playthroughs shouldn’t take anywhere near as long… unless you’re playing on Maximum Security difficulty, where additional deaths begin to stack up in one of the best PC games of 2022.
