Dungeon Defenders: Second Wave (see what Trendy did there) will be released as a free update to the iOS versions of Dungeon Defenders: First Wave [$2.99] tomorrow, the developer has told us via an e-mail release. According to Trendy, Second Wave addresses "many of the issues" from the first game, including the horrendously cluttered UI and clunky menus that kept us from enjoying its first try at an iOS port of its downloadable game.

In addition to these improvements, Second Wave will see "performance improvements," and a player-versus-player content package called "Arena." If you pop out your eyeglasses, you'll be able to see some of these tweaks and adds in its newly-released trailer.

In case you didn't know, Dungeon Defenders is now available on Xbox Live Arcade and as a PC release on Steam. These versions are particularly good according to media types, so you might want to consider checking those out if you're into the game's hack-and-slash meets tower defense action.
