UPDATE: Dead Island: Epidemic will release in 2014, Deep Silver has confirmed.
"I can only recommend giving dead island epidemic a try," Deep Silver creative director Guido Eickmeyer said in a Reddit AMA. "Honestly, I love this one and it will be out next year. So whilst not being an MMO, i think you should have a close look. Especially if you are an multiplayer entusiast [sic]."
ORIGINAL STORY: Deep Silver has announced Dead Island: Epidemic, a free-to-play Zombie Online Multiplayer Battle Arena game - or ZOMBA - heading to PC.
Dead Island: Epidemic sees three teams fighting against each other in a "desperate fight for survival", and is said to feature "all the trademark elements that are part of a Dead Island experience".
It isn't yet known who is developing the title, or whether Dead Island creator Techland is developing it in tandem with Warner Bros' Dying Light.
