Little-known Korean publisher Aprogen Healthcare & Games Inc. recently announced the Closed Beta phase for its new mobile action RPG, Soulworker ZERO. Aprogen Healthcare & Games Inc., as its name suggests, actually has a business in biomedical technology and even a stake in the wireless communication industry. Based on the anime PC MMORPG Soulworker developed by Lion Games, Soulworker ZERO is actually created by another little-known Korean studio, VisionBros. This mobile version apparently uses the same story, and the Closed Beta will run for just a week in South Korea through the local ONE Store.
