BEATING LOKI: Use the Odin ship with the Excalibur weapon and dodge/shoot until "device overdrive" special is charged. Then abuse Odin's invulnerability to get to 200k chain so you score 50%+ bonus to special when invul wears off. Survive until you can fire special a second time. That last special should get you past him. To unlock Odin, beat lv20. To unlock excalibur, beat lv19 with only the first weapon (not as hard as it sounds with upgrades - if you need easy gold, play lv18 over and over). IF THIS HELPED COPY-PASTE AND KEEP IT ALIVE
@michaelbomber: A borg cube is a type of ship that you can sometimes find in the Vex system. It is also a playable easter egg. It is armed with a deadly cutter beam which if you see any romulan ships around, you will see that the damage is tremendous. It is a big giant cube....
Base wars is actually pretty simple.
All you need to do is to take over one star in each base and put a fighter base in there. The compter uses a lot of economy and naval stars in ther and when a fighter takes it convert them all to fighter bases
