Root Automata & Underworld Live!

About Root: The Clockwork Expansion, from BoardGameGeek:

Root: The Clockwork Expansion allows players to square off against four fiendishly automated factions. Insert a faction to round out a low-player count game or team up for co-operative play! Compete against the: Mechanical Marquise 2.0 - Dodge her marauding patrols as you try to stop her from completing her building tracks. Electric Eyrie: Shore up the Woodland's defenses against this fearsome invader. If they go unchallenged, the Woodland will soon be flooded with their forces. Automated Alliance - Police these radicals and raze their bases before a little uprising turns into a massive rebellion. Vagabot - Hunt the dastardly Vagabot across the many clearings of the game or attempt to court him with items.
