The Level Up - Expansion brings several new elements to your board, the most notable one being the solo mode. We felt that if you played a solo mode, you don't want to play a reduced version of a cooperative game. You want to use all elements of the game - and since all expansions are compatible with one another, you would want to use all the material from all the expansions, right? Inside Level Up you'll find the rules for the Solo mode. In this new game mode, you'll take on the night shift alone. But you'll get help not only from staff members, but also from automated HEROes that you either chose or select randomly before the night shift starts. These automated HEROes can counsel with you, treat patients on their own and hence add to the feeling of a real night shift. In the expansion, you'll also find 4 brand new HEROes for you to play - in all available game modes for HE.R.O. These four have been on many adventures together and for some reason, they got thrown into a board game and have to face a night shift now. There's also 15 new patient cards and 5 more diagnosis to add to your copy of HE.R.O - so you'll face even more different patients and have to adapt. —description from the publisher
