I'm one of the devs for that, thanks for mentioning it!
2 factions with tiered factories instead of the "flat" balancing, and instead of using the local energy grid for Overdrive you build Metal Makers that convert energy to metal for you.
That said the enemy AI seems to have a bunch of neat tricks up its sleeve. And it feels like TA-in-3D.
Also, I wish the developers would spend some time making the UI feel a little more lively.
