Aurora is a space exploration roguelike game, heavily inspired by Star Control 2 and Prospector. Player takes command of a scout starship, that is sent from Earth to explore outer space, establish contacts with other species and bring anything valuable back home. And when we say 'scout starship' we don't mean that small unarmed one-man thing. We mean a real ship, with dozens of crew members, with on-board laboratories and workshops and its own military regiment.
Player progress is tracked by Earth government, in case of poor performance game will be over. Good performance can affect the development of a solar system. See how new ships and stations appear there, that use technologies discovered in your travel.
However, deep space hides not only treasures, but also threats, that can be deadly not for a single ship, but for the whole human kind.

Looks quite interesting---been quite some time since somebody attempted something approaching this scope in Java at that.
