Star Trek - Bridge Commander

Sequel to Galactic Empire. A.G.E. (= Advanced Galactic Empire) is an early first-person space/adventure hybrid from Coktel Vision. Both games sports a fast 3D engine. As you pilot your spacecraft around the planets and stars, engaging in space combat and conversation with other characters, you unravel the Conquer the Universe plot. The game is similar to Elite in that you are relatively free to travel to wherever you please.

In the 24th century, on the frozen Jovian moon of Europa, earth has established a colony to extract water from the moon. One of the mining facilities accidentally discovers on their excavations members of a long-buried alien race. The creatures, now awake, slaughter all the miners and destroy the moon's capital city. It's up to you now to defend what's left of the colony and eliminate the aliens, or at least hold them off until help arrives. Gameplay consists of 3D space combat action (though mostly on the moon's surface) with a twist: you don't play a specific character or campaign, instead you are placed on the shoes of different characters with each new mission. Each trying to do their best to survive using 7 different vehicles, from starfighters, to recon scouts, to ground-based turrets.
