We tried co operation: Multiturn (not the greatest name from a discovery standpoint) and had a great time, all you have to do is get the patient in a bed and medication to the patient, easy right?

you have to plan your moves ahead and talk to you friends to make sure the patient you just threw gets caught and doesn't go sailing out of a window.

Up to 8 people play on phones as controllers so you don't have to work out the logistics of 8 usb ports etc.
