Deep Silver has announced that Dead Island has sold over 5 million copies at retail since the game first launched September 2011. Dead Island made a large splash with its CG trailer debut and a sequel, Dead Island: Riptide, is planned for release later in 2013.

“This once again proves that venturing into new waters in terms of games publishing does matter for success and that even at the end of a console cycle new IPs can be created and nurtured into lasting franchises,” said parent company Koch’s Menno van der Bil.

“The continued success of Dead Island has proven that we’re on the right track with our overall IP strategy for Deep Silver” added Koch CEO Klemens Kundratitz. “This once again proves that venturing into new waters in terms of games publishing does matter for success and that even at the end of a console cycle new IPs can be created and nurtured into lasting franchises.”
