Although sometimes I grow tired of a particular game by the time I reach the DLC content, I decided to give the Usonian (USA) campaign a go.
The biggest change is the introduction of aerial units. You can see though, that it’s a DLC, because most of the units are similar for all factions. But US has a few unique ones.
Storytelling continues to be amazing. It’s a bit tongue-in-cheek, with US first “protecting its assets” (oil refineries) on Alaska, at the outbreak of the Revolution in Russia. Then cosplaying Lawrence of Arabia.
Arabia has just two unique units. Hashashins are close-combat ninjas, effective at countering enemy infantry, most of which weak in close combat. And war camels, as funny as they sound, are able to outrange and supress any infantry, and escape any enemy mech. In a game where all the units are slow, a fast unit is a game-changer.
