If you haven’t yet finished Chapter 2 of The Tales of Monkey Island you should probably get going on that. The third installment arrives September 29th and will be called The Lair of the Leviathan. Lots of piratey goodness in that title.

The release date is only for the PC version of the game. As with The Siege of Spinner Cay, you’ll be waiting on the 360/Wii releases just a little longer.

Along with the expansion of the new game, you can find Guybrush Threepwood’s original adventure, The Secret of Monkey Island on sale from Steam and Direct2Drive this weekend for $5. The sale coincide with Talk Like A Pirate Day, September 19th. The sale will run until the 21st, so you’ve got a few days to decide whether you can part with honest Abe.
