Easy kills in Skirmish mode
On any stage in Skirmish mode, get into a confrontation with your enemy, then turn and warp all your ships to the corner of the map. If done correctly the enemy ships will attempt to follow and warp directly into the corner of the map and become stuck. Depending on which ship it is, the enemy will not be able to fire back at your fleet. Some enemy ships will only be able to use their rear phasers and torpedoes. However, this trick rarely works with the Borg.

U.S.S. Voyager
Use the following trick to get the U.S.S Voyager as a usable ship during Campaign mode. Buy three Intrepid class ships. Notice that none of them are named Voyager. Sell the last ship you bought then re-buy it. More than likely, it will be named with the same name. Do this about four to five times quickly and you will find the U.S.S Voyager. This is the only way to get it as a usable ship in Campaign mode. For it to actually have Kate Mulgrew as its Captain's voice, you must have luck.
Unlock the U.S.S. Legacy
To unlock the secret ship "U.S.S. Legacy" (and receive the achievement); beat the game once on any difficulty then load your game. When you do; you should be on the ship buying screen right before the final mission. From there; sell and/or buy ships to make sure you have 3 Sovereign class ships. The final ship you buy will be the USS Legacy.
