4 players (bridge crew) controll one star trek ship. There are 4 stations on the bridge. Helm: steers the ship. Tactical: Manages weapons and scaning. Engineering: Repairs the ship and manages energy. Captain: Holds everthing together and is the only one with detailed info abour all ship systems. Then there is system intrusion and beaming which can be performed either by helm, tactical or engineering.
Each station isn't complicated to handle, but working together and communication is nassacary because each station has only access to specific information and functions. For example only helm and the captain have informations about the detection radius (the area where enmy ships are able to detect your ship) and going into 'stealth' to sneak through enemie lines is often vital. The move controlls are very well done and seeing other people working on their own terminals in real time while the ship is under fire and shilds begin to fail is awesome. Playing the game feels like sitting on a star trek holodeck.
