How many GB is Old School Tower Defense?

0.29 GB

That is less than the typical Strategy game, which needs about 3 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.

Build and upgrade towers with unique abilities to stop waves of enemies. With the advanced augment system, every 3 rounds you can boost your defenses and create strategies that fit your playstyle.
