How many GB is Fallout 3: Mothership Zeta?

7 GB

That makes it bigger than 60% of Shooter games we have measured.

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

Leave at least 14 GB free: games need headroom to unpack updates.

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

Defy hostile alien abductors and fight your way off of the massive Mothership Zeta, orbiting Earth miles above the Capital Wasteland. Mothership Zeta takes Fallout 3 in an entirely new direction – outer space. Meet new characters and join with them in a desperate bid to escape the Aliens’ clutches. To do so, you’ll wield powerful new weapons, like the Alien Atomizer, Alien Disintegrator, and Drone Cannon, and deck yourself out in brand new outfits, like the Gemini-Era Spacesuit and even Samurai Armor.
