Dead Island: Riptide, the pseudo sequel to paradise-gone-wrong simulator Dead Island, shares one clear trait with its predecessor. No, not zombies (but, yeah, those are in there). It's that reviews are all over the place for the game's launch. The original Dead Island entered into a similarly hostile critical climate, but went on to sell 5 million units globally. Our Riptide review will be available later this week.

• Game Informer (80/100): "Riptide's flaws are many, but they couldn't hold me back from having a blast. Few games nail the visceral feel of melee combat and co-op fun like Dead Island. At its worst, an annoying hiccup breaks the immersion of the grizzly trek through a zombie-infested paradise. At its best, Riptide hits the same high notes as the original."
• IGN (72/100): "Technically, it's done nothing to build itself into a great game. Rather than fix the graphics and the performance problems that plagued the original two years ago, Techland slightly modified the setting and delivered a new character and more content. It's a fun time, but there are no surprises or killer new features to make it an impressive package."
• Eurogamer (60/100): "What makes that so sad is that this feels like a series only a few great decisions away from being really good. A better script with a sense of humor, a bit more imagination in quest design, more coherent inventory management and character development... These things shouldn't be unattainable goals for a developer that must be flush from the unexpected success of the first game."
• VideoGamer (50/100): "On the whole however Riptide is yet another missed opportunity, and just too painfully average, wonky and padded out with filler to truly recommend."
• Gamespot (40/100): "Riptide is dumb, and mind-numbingly slow, and somehow manages to make the art of zombie-slaying feel like utter tedium. And if slaying zombies isn't fun in a game that's all about slaying zombies, why bother? "
