How many GB is Isyium?

0.22 GB

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

Leave at least 6 GB free: games need headroom to unpack updates.

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

Isyium is a unique combination of simulation, strategy and casual arcade (if played in that spirit) with an abridged story mode. Set in an orbital accelerator many years in the future after Earth's untimely bio destruction, you pilot a futuristic - if not altogether rusted and clunky apparatus - called the Spinnercast Module, capable of near light speed.
