Vector Unit has announced the first DLC for Hydro Thunder Hurricane. The "Tempest Pack" will offer three new environments, two all-new boats, a boatload of new skins, plus Championship, Ring Master and Gauntlet events. The environments will have you racing through the ruins of Atlantis, the stormy Bermuda Triangle and a medieval setting named Castle Von Boom. The new boat skins will supercharge the existing boats, allowing you to run even your favorite clunker at the game's highest speeds, with two of them coming straight from the Design-a-Skin contest held a while back.
No final date or price yet, unfortunately, but you can look for the pack sometime in October.
