Dungeon Defenders started out as Dungeon Defense, a free to download UDK game from the [http:/www.udk.com Unreal Development Kit] Showcase. Dungeon Defense was only a proof of concept, and required additional full-scale development work to be turned into a salable game. While Dungeon Defense took a mere four weeks to create, Dungeon Defenders took more than a year to reach public release after being announced in August, 2010. The game combines elements of the Action RPG and Tower Defense (Concept) genres.
Cross-platform play between PS3, PC (Platform) (via Steam (Concept)), Android (Platform) & iOS systems was announced, but as of Jan 2012, this feature has still not be fully integrated. On January 4, 2012, Trendy Entertainment's twitter account--in responding to a question--verified that PS3 and PC cross-platform play is not currently possible.
On 19 December 2012, Dungeon Defenders was released for Mac OS and Linux as a part of Humble Indie Bundle VII.
A version of the game was also announced and being developed for the PlayStation Vitabut was later cancelled by the developer in an effort to divert resources towards the development of another game.
The game is set in the world of Etheria (Location), where four legendary heroes have defeated a great force of evil called The Old Ones and sealed it inside the Eternia Crystal. Those heroes then set off once again seeking new adventures, leaving behind at their castle each of their four young children. While playing one day, these children accidentally break open the Eternia Crystal, releasing the Old Ones back into the world. Following in the footsteps of their parents, the children must now work together to fight off the hordes of monsters advancing on their castle home.
There are four unique player classes in Dungeon Defenders. Each of them has 8 common stats that can be upgrading by spending skill points, earned upon leveling up. Additionally, they each have 2 unique skills that must be unlocked before they can be used or upgraded. Each character also has four unique towers that they can build. Each class has a capped level of 78.
