Star Trek Legacy

There is a bug in the AI of the enemy ships in this mission that you can exploit. It's a bit tedious, but guarantees all the ships survive and makes the mission a cakewalk, even on Admiral difficulty.

At the start, select just the Enterprise, then move toward the left side of the turret wall. Pull up to about 1500MM from the leftmost one (facing the wall, not coming from the side), stop, transfer power to weapons, and open fire. After destroying a couple turrets, the enemy ships will come up to you. But here's the weird bit: They will fly to about 700-800MM of you, and just sit there.

Select the ships with RB (not A) to make sure you don't accidentally move. They will be sitting ducks and easy pickings. More ships will come, but they will eventually run out. After they run out, destroy the shipyard near the turrets. The fleet will rush in virtually unopposed, allowing you to retake the station easily. When the ships in the rear shipyards attack, your fleet will shred them in seconds.

Once you start blasting the enemy ships while stationary, make sure you do not move from that position, or they may open fire. Also, do not select another ship during your attack, or the Enterprise's AI will kick in and start moving.

First, of course, play on easy. Second warp all of your ships to the turret field and start engaging the turrets right away. It's important to stay out of the nebula as it can destroy your ships rather quickly. You will likely need to retreat and repair frequently especially if you are going for the Antique Collector achievement and are using only three vessels. Once the grid is down destroy the repair yard to activate your allied ships. From here just follow the objectives. If one of your allies ships does get destroyed (which is unlikely on easy) just restart the mission, and make sure you don't save if you complete it.
