A new trailer showcasing Dead Island's summer vacation gone bad has arrived, but this time, we get a glimpse into the cooperative portion of the game. It makes sense, since developer Techland has promised that the game's main story-based campaign can be played through with up to four tasty zombie treats people. The new trailer also reinforces that fact that zombies in bikinis are kind of disgusting.

While the four protagonists might not be as immediately charming as those starring in parts one and two of another well-loved zombie series, Dead Island's protagonists aren't without personality, and the open-world nature of the island is undeniably alluring.

For more information about what to expect from Dead Island, our three previews should help in that regard. Xav previewed the game first at GDC, I played a bit in-house, and Ozzie got his hands on the aforementioned co-op component at E3.

Dead Island is due out on September 9 for PC, Xbox 360, and PlayStation 3.
