Today Telltale Games released the third installment of episodic adventure series Tales of Monkey Island. Lair of the Leviathan can be purchased digitally for the PC through TellTaleGames.com and Steam.

Leviathan continues Guybrush's journey to rid the Caribbean of a terrible pox. Unfortunately, he's hit a bit of a snag: his ship has been swallowed by a giant manatee. He needs to find Voodoo Lady's ex-boyfriend, de Cava, who went in search of the artifact that could stop the pox some time ago.

The episode will be released for the WiiWare soon as well. There's usually about a two-week delay between the PC and WiiWare releases so expect it in the second week of October.
