Dead Island - Coming September

Falchor writes that if we follow Borderlands /2, we should also follow Dead Island. I don't think there's any doubt it's not actually an RPG but an open-world zombie game with RPG elements (and 4-player co-op) might be worth a look for some. Details at the official site and here's an old preview from Eurogamer:

And Dead Island revealed itself to have a hunger for stats as voracious as any of its stumbling horde's taste for flesh. Alongside being an open-world, first-person adventure and a four-player survival game, it's also a loot-happy RPG. In fact, it's unfair to call it a zombie game at all: Dead Island's more of a Frankenstein's monster, sewn together from ideas from the undead genre's prolonged flourish and brought to life with a little spark of Techland's own.

Its debt to Valve is told from the character selection onwards. Four playable characters are available, all drawn from crude clichés, endearingly patched together. There's Sam B, the former rapper who wakes drowsily from a heavy night to scenes of carnage at the game's outset, Xian Mei, a receptionist on the island, ex-pro footballer Logan and finally Pruna, the fourth character of which little has been revealed.

They're more than just colourful re-skins, and Dead Island's RPG credentials seep through each character's abilities. Sam B's the tank, able to soak up more damage but conversely attracting more of it, with more of that coveted flesh hanging off of his bulky frame, while Xian Mei is fleet-footed but more prone to damage. Logan, meanwhile, is an all-rounder, with Pruna a firearms expert.
