Dead Island
The plot of Techland's recently announced Dead Island promises a fun time: a tropical tourist resort turns into a zombie apocalypse. You, as a tourist on the package holiday to hell, must put things right and bash the horrors. It's cocktails and crowbars on the beach as you battle with decomposing partygoers. Yum.
Techland promise open-ended first-person survival shootiness in a large island environment. Using the environment to drop things on zombies, and to find clubs to beat them with looks like it'll be the order of the day. Your overall objective is to find your lost wife, who was presumably out shopping for a nice beach towel before the arrival of the undead. So it's a sort of Stalker-comes-to-Hawaii. (Could the twist be that you are your own wife?)
I'm betting research was fun for this game: "Yes, we all have to go to a tropical paradise island for... authenticity." Techland are also boasting "a liquid, gas and electricity physics simulation system, which allows you to create your own unique ways of eliminating enemies", which is a claim I'm sure I've heard somewhere before...
