Spice up your Mechanica factories with devious new inventions to build around and harmless robotic overlords to cater to! Contains 10 double-sized Invention puzzle pieces that players bid on at the start of each game and add to their factory. From the Teleporter that can move bots to anywhere in your factory, to the Nanobot Converter that destroys bots and gives you money, each invention will change the strategy and layout of your factory! 12 Overlord cards of which players are dealt 2 at the start of each game. Overlord cards are your completely trustworthy and totally not terrifying bosses at Mechanica. Each overlord wants you to build your factory in a particular way, and will give you a bonus based on how well you meet its request. At the end of the game, each player chooses one of her overlord cards to score, and discards the other. —description from the publisher
