Compounded: Chemical Chaos is an expansion for Compounded released in 2013 for 2–5 players, 30–90 minutes per game, and ages 13 and up. It was designed by Darrell Louder and its main mechanics are Push Your Luck, Trading, and Area Movement.
The Chemical Chaos promotional expansion pack adds 14 new Compounds and 1 additional Lab Fire to your game of Compounded (marked by chemical element symbol in corner of cards). These mix in more strategic play and chaos to the game. When playing with the Chemical Chaos expansion pack, remove the starting Compound cards from the game. Shuffle the 14 new Compounds into the Compound deck and set up the starting research field with all random Compounds. Then separate the deck into 7 stacks and add the 6 Lab Fires. Game play then continues per the normal rules. Contents: 1 Lab Fire 3 Isocyanic Acid 3 Cyanogen 3 Disulfur Dinitride 2 Hydrogen Cyanide 3 Hydroxylamine
