You Sank My Dreadnaught! Achievement
You Sank My Dreadnaught!10
Destroy an enemy dreadnaught in a multiplayer game.
Your opponent will first have to research far enough to unlock the dreadnaught. Then they need to build one and you have to destroy it. This achievement is best gotten along side the "Overwhelming Force" achievement, which requires you to build a fleet containing 5 or more dreadnaughts. Research the dreadnaught blueprint, then build a fleet with 5 of them. Use this powerful fleet to take on your opponent's single dreadnaught fleet. This will unlock both achievements.
