Much like other dungeon crawlers, you'll take the role of one of the four classes, fight off tons of monsters, grab lots of loot and progress through the game by buying gear, leveling up and having a good time. Now that Steam Workshop support has been added, community based mods and other goodies should add to the longevity and enjoyment of the game.
The deal is live now but only until April 8. You'll need the Steam client to download and install.
