How many GB is Thunderbird?

2 GB

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

Thunderbird is a classic arcade-style STG. You will be the pilot of the space fighter, stepping onto the space stage, engaged in a war between many forces. Fly a fighter jet, experience the speed of a shot under fire, or learn the truth behind war.
