Nexus: The Jupiter Incident

At the dawn of the 22nd century, the solar system was being controlled by huge corporations. One of these corporations has woken up something big at the edge of the solar system. Chaos ensues and it's dubbed as the "Jupiter Incident". You take the role of Marcus Cromwell who finds himself in the middle of the conflict. Nexus is a real-time mission-based tactical space game. Think of Ground Control set in space and you get the picture. The developers call it a Tactical Fleet Simulator (TFS) and the first of it's kind. Nexus boasts a powerful Black Sun engine and supports both DX8 and DX9 shaders. In addition to the campaign mode, the game has LAN and online multiplayer modes.
