How many GB is Mantle?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Alert! It's time to rise to the occasion. Every nut and bolt is fitted. Every high-tech gadget is primed. Step forth, Mantle, and become the greatest superhero robot ever…hopefully. Face off against good and evil and discover who the true villain of your story is.
