Well this was the idea: "You are a parasite looking for the ideal new home! But you are not alone in your search. Use stealth and guile to beat your rivals to the perfect host! 4 player king of the hill style game, each level will have one perfect human host, but it can only fit one of you, so you must battle for control and avoid being left out in the cold." Currently, you can run around, finding the perfect NPC for yourself. You can steal other people's.
