Are there any secrets to the game? So far, I've discovered a tactic to destroy virtually any ship with anything as good as a Corvette, I've killed the alien cruiser (with a Kestrel), and ran missions to receive a tractor beam, and cloaking device.
If you're wondering about that tactic to kill things easy, it's simple. Just let the enemy chase you. After letting the enemy shot off all missiles/torpedos, get the enemy to chase you, but not catch you. Turn around an shoot, but don't stop your ship. Try to stay slightly out of your enemy's range. Since he is chasing you, shots from your ship will hit him, but his shots won't hit you. Occasionally, the enemy will stop chasing you and wait for your to move in the enemy's direction. Move slowly in the direction of the enemy. Once the enemy starts to chase you again, take off so that your are again positioned in front of him (where your shots hit, but his doesn't). I was able to destroy multiple Confederation Heavy Crusier in a Corvette with this tactic. I bet you could take out a Confed Cruiser in an upgraded Argosy or possible a Lightning, but I haven't tried it yet.
Are there any other missions I can run for the Rebelion? Like a mission to attack Confederation space? The last mission I played for the Rebelion gave me a tractor beam. I was told to find a use for the tractor beam. So far, I've found that it's great for catching little ships (like alien fighters) and killing them. I've already got 1/3 of the galaxy paying me tribute, but I'd rather run Rebel missions.
