Inc Gamers preview

“In an attempt to combat this threat your arsenal is seemingly underwhelming at first but actually packs quite a punch. Your instruments of pain infliction consist of whatever is lying around the island, meaning you’ll be fending off the hordes with oars and planks of wood – if you’re really lucky you might find an axe or a machete.

I tend to get suspicious when someone says ‘this is not a fully fledged RPG’ after that same person has just finished demoing a game in which you pick up a wealth of what seem to be useless items before hauling them to a work bench and begins assembling them into some new-fangled zombie mangler. Dead Island’s work benches take you to a menu screen from which you can craft, repair (weapons have individual damage, range and force stats) or upgrade weapons. After some tinkering the simple machete was transformed into an electric-machete and some knives were kitted out as sticky bombs by attaching some form of explosive to them.”
