It began as a free demo to show off the use of Epic Games' Unreal Developer Kit tools but now it's being reworked as a full commercial game title. Developer Trendy Entertainment has announced its plans to release Dungeon Defenders, a action-RPG-tower defense hybrid title, via download this fall.

The game was previously released last February as a free UDK demo under the title Dungeon Defense. The UDK demo reportedly only took four weeks to develop. The full version of the title under its slightly changed name will feature 15 levels and a "watercolor art style" in its depiction of a fantasy-themed tower defense game with a number of action and RPG elements including "character leveling and customization, awesome loot drops and plenty of team-oriented defensive strategy." There's also support planned for four player multiplayer via online and LAN. The title is now available for pre-order at GamersGate and Impulse and both are giving a pre-order discount of 10 percent off its regular $9.99 price.
