I'm hoping to get Quintet on Steam! Once it's there, I can add some Steam specific features (like having a single login and achievements).

Quintet is a scifi cooperative, cross-platform, multiplayer, "crew" game where players work harmoniously to control the same ship. There are 5 roles: Captain, Helm, Tactical, Engineering and Science. There are multiple types of ships for 1 to 5 playes per ship. All of the different ships can play with (or against) each other in the same missions. Windows, Mac, Linux, Web Browser and Tablet/Mobile users can all play together! You can all play over the Internet or on your LAN as well.
