In the new expansion their are more upgrades, consumables, power sources and New Sabotage Cards.
These are all mixed in with the cards from the original game and the game is played as before. On your turn you now have the option to play a sabotage card (if you have one) on an opponents machine these are played like any other card but can only be played as plugs. Throwing a spanner in an opponents works helps even out the game making it a little longer but keeping it interesting.
This is a fantastic little expansion which adds an interesting twist to the original game.
