This is the intro of the main campaign. It shows some ships, that are in the game as well as the ability to create movies within the game engine.
This is a gameplay video of the fourth mission in the fourth campaign (Pirate business). You see the briefing and debriefing of the mission, some flying, fighting and scanning, hyperspace jumps, commanding other ships...
In the second gameplay video, you see the third training mission (SpaceGuards training). Here your character learns how to do hyperspace jumps. As often happens, there are some unpredicted events in this mission.
Here is a test setting with 1100 asteroids in a ring system. There are also 20 fighter ships (10 Terrans and 10 Spacer), that fight each other. The game does a collision detection of all space objects and the lasers, that are fired by the ships. With all calculations and the drawing, I got about 30 fps on my system.
