A tip for those who are finding it hard to beat the mission because of how far they are away from the Titan! Instead of trying to move ahead at them, which will only result in you being late while you are being fired upon by their fighters, turn to your side and strafe. You quickly leave the enemies in the dust and will make it to the Titan with plenty of time to spare!
At the Mission Selection screen, press up, left, down, right, up, right, down, left, up, then simultaneously press L1 and R1, then L2 and R2.
During Mission 6A "Piercing Encounters", you can get a nifty little adjustment to your debriefing screen. Let the Borg win and take over the Typhon. When Worf starts telling you about the failed mission, the Borg machinery will start taking over the screen. Nothing really too important as far as gameplay goes, but it's a nice extra.
