The new Heavy Destroyers feature an enhanced version of the transformation ability present in the earlier versions along with a specialist officer bridge seat and the new Weapon System Synergy trait, which buffs projectile weapons after concentrated barrages from energy weaponry. If you desperately want the new ships but aren’t a veteran, you’re in luck; it’s not a coincidence that they’re being added to the game at the same time that a sale on lifetime subscriptions is being offered.
Star Trek Online have long had access to a special ship that shows off their elite status. Unfortunately, the game’s most recent patch has left that ship a bit less elite; you can upgrade your Heavy Destroyer, but it’s still just a Tier 5 ship instead of a Tier 6. So it’s good news that a new Tier 6 Heavy Destroyer is being rolled out for all three factions, allowing long-time players to unlock a new starship trait and take on space with an improved craft.
