How many GB is Doom: The Dark Ages?

100 GB

That makes it bigger than 98% of Shooter games we have measured.

The median Shooter game needs 4 GB; the largest tenth start at 40 GB.

Leave at least 125 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

A single-player first-person shooter and prequel to Doom (2016). Set in the dark medieval world of Argent D'Nur, players control the Doom Slayer in a grounded, weighty combat style that emphasizes strategic engagements over the acrobatic mobility of previous entries. The game introduces a Shield Saw for blocking and parrying, new melee weapons, and drivable vehicles including a cybernetic dragon and a massive mech. The narrative focuses on the Slayer's origin story with expanded cutscenes and character development.
