How many GB is Altus Chess: Archaic Beginnings?

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.

Classical chess plays one move at a time. Altus plays in resonance. Link pieces through quantum-inspired entanglement and trigger cascading resonance reactions across the board. A premium single-player chess experience that preserves every classical rule while dramatically raising strategic depth.
