How many GB is Calyx?

4 GB

That is less than the typical Real Time Strategy (RTS) game, which needs about 6 GB.

Leave at least 10 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 strategy game with a new kind of enemy, Calyx puts you in charge of a space mining outpost, locked in battle with an overwhelming alien organism. Build your base, gather resources, assemble your forces, and take on the Calyx. With only an out-of-date AI for company, can you survive?
