Torchlight II finally has a firm release date.

It will be released on September 20, Runic Games announced via its forums.

The game was originally due out in 2011.

It features twice as many player skills, three times as many boss battles, and six times as many unique zones as its well-received predecessor, and is four times larger overall, Runic has said.

Torchlight II is available for preorder on Steam for US$19.99 (AU$19.35).
