The Generator is a common structure built by players, as Energy is highly sought after for Forge players or the Arsenal structure. It can later be upgraded into the Solar Grid.
The energy produced by this structure is greatly helpful for all structures in the Forge line, as they all cost a healthy amount of Energy.
Unlike the Treasury, this structure comes with a very powerful modified sakata unit that in the early and mid-game is a dangerous threat and base killer with incredibly health regeneration.
