In Skirmish mode, get into a confrontation with your enemy, then turn and warp all your ships to the corner of the map. 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 you. Some enemy ships will only be able to use their rear phasers and torpedoes. Note: This trick does not usually work with the Borg.
To get the U.S.S. Voyager for use in Campaign mode, first purchase three Intredpid class ships. Sell the last ship you purchased and then re-buy it. It should have the same name. Do this about five times quickly and you should have the U.S.S. Voyager.
