How many GB is Marimo vs. I.A.S?

1 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 7 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 2.5D shooter with old-fashioned side-scrolling and a way to attack enemies in the background. Fight with lock-on shots that can track up to 6 enemies appearing from the back of the screen at the same time, and forward charge shots that can penetrate enemies and enemy bullets.
