Rivet Wars: Reloaded – Nemoan ExpansionExpansion

From BoardGameGeek:

The Nemoan Expansion adds a third playable faction to the Rivet Wars: Reloaded core game. In most cases, Nemoan units are more expensive in deployment and rivet points than their Allied and Blight counterparts. They've also got a little less variety in unit types. That said, their advanced technology and unusual battlefield tactics give them an edge. They're strong, versatile, and you'll often find fewer of them on the field.
