Doom: The Dark Ages is the latest entry in id Software’s modern Doom trilogy, acting as a prequel set in a medieval-inspired era. While it trades sci-fi tech for retro-style melee weapons and gritty armor, the signature fast-paced gunplay is still front and center.
If you’re wondering how long it takes to beat this brutal single-player campaign and what missions you’ll face, here’s everything you need to know.

How Long to Beat Doom: The Dark Ages
You can expect to spend around 17–20 hours completing Doom: The Dark Ages. That estimate assumes a playthrough on normal difficulty with some exploration for secrets and side content—but not a full 100% completion on the first run.
- GameSpot reviewer Alessandro Barbosa took about 18 hours to finish the campaign while engaging with some optional objectives.
- The final playtime will vary depending on your chosen difficulty, playstyle, and how much time you spend hunting for collectibles and secrets.
- The game features a level select option, so you can go back and replay missions to mop up anything you missed.
