How many GB is Express 404?

1 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

Drive a storm-ridden night train, manage your speed and your passengers — one of them is a mimic. Build powerful upgrades between stations, reach dangerous quotas, expose the monster, or profit from chaos in this roguelite paranoia simulator.
