NDOORS Interactive has released the closed beta client of WonderKing, a casual MMO designed to appeal to teenagers and pre-teens - ages 12 to 15 - looking for a light, engaging online experience. Players will challenge the demonic forces of Valron in real-time combat as they strive to become the "Wonderking" that will bring light to the shadows of darkness. There is a wide variety of customization available from clothing to facial features and hairstyles. WonderKing will be free-to-play and offer players the ability to acquire tools, weapons and mounts from the item mall. WonderKing will launch in the second half of 2009.
