Publisher Deep Silver has released the first details and screenshots of Dead Island: Riptide.
The game's set for release on Xbox 360, PS3 and PC in 2013. Here's the official description, which you probably won't want to read if you're still planning on completing the original:
The survivors of the zombie-apocalypse on the once beautiful island resort of Banoi escaped in a helicopter to the safety of a military ship. When a furious storm hits and the virus suddenly spreads throughout the crew, the nightmare starts all over again, leaving hope drowning in the rising tides.
Devastated by a monsoon, the island of Palanai is crawling with new zombie mutations. A fifth character with an all-new skillset will join the team, providing much needed support. Additional multiplayer communication features and brand new hub defense missions will test the survivor's teamplay skills.
