About fighter manoevres: Fighters can use the enemies shield to quickly shed velocity. This is a dangerous manoevre and will damage the fighters ship if done incorrectly.
Shield: A shield forms a Bubble around the ship. Fighters can fly inside it and launch missiles from there bypassing the shield. Any other ammunition that fails to pierce the shield.(Either through damaging it till it deactivates or by having shieldpiercing) will do no hull damage.
About crew teleporters: They exist, and work in a similiar way of teh jumpdrive. Since Jumpdrives will actively try to prevent things from jumping in near them(to prevent 2 ships from jumping on top of each other.), teleporters are often very large and energy hungry, in order to be able to suppress the enemies ship jumpdrive.
Jumpdrives: Allows jumping towards a beacon. Jumping whitout beacon is dangerous. A jump drive can safely idle at 50% charge, but any more might destabilize it resulting in an uncontrolled and/or partial jump.
Sector C 27: A sector consisting of nothing more than empty space and a single resupply station(Untill you blew it up). There aren't many ship that visit this station.
Galven V: The fifth planet in the Galven system. The only beacon in the system is located here. Galven V is a gas giant, and used to be one of the mayor fuel producers in the regio. Nowadays it's atmospheric stations are home to a thriving black market. Rumour goes that several pirate groups have bases here. Legal action here isn't likely, because the defence systems installed by it's previous owner are still online and functioning.
