Nexus -- The Jupiter Incident is what we call a TFS: a Tactical Fleet
Simulator. It's like nothing you've played before. The strong,
elaborate story takes you from mission to mission and allows different
approaches. It's up to you which tactics you choose to bring each
mission to a good end. A reward system enables you to repair, upgrade
and enhance your ships depending on the approach you chose. Mission
briefings let you roam through an unbelievably accurate 3D animated
star map system.
