How many GB is Iron Onslaught?

2 GB

That is less than the typical Fighting game, which needs about 6 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.

Iron Onslaught is a wave-based game where you survive an endless wave of bots and mechs, and the only way to survive is to kill to unlock new weapons before you're overpowered by them. So sit back, relax, and survive the ever-growing horde.
