Warline: Dragons War

From BoardGameGeek:

In this solo / two-player-cooperative expansion for Warline: Maneuver Strategy & Tactics, command your army in an against-all-odds struggle versus supermassive Lesser Dragons. Dragons War features the core game's "Strategicraft" setup-is-gameplay systems and rich battlefield mechanics - and adds a quick, easy to operate Lesser Dragon "automa". As you command your army successfully, the Lesser Dragon's life is depleted, but the dragon's power grows. Gameplay is tense, strategic, tactical, and brain burning. Also included in Dragons War are two new kingdoms (factions): the Kingdom of Blud ("Blood") and the Kingdom of Goyld ("Gold"). These kingdoms expand the mastery ceiling of Warline with their own new asymmetric abilities and play styles. The Blud kingdom sacrifices its own units to build tremendous power. The Goyld kingdom exerts its infinite wealth to hire on an endless swarm of unscrupulous mercenary troops. Blud and Goyld can be played in both the Dragons War expansion and the base game. -description from the publisher
