To pre-empt your first question, no, Dead Island 2 was not worth waiting eleven years for. In its defence, however, few things are. If George Romero had taken over a decade to make Night Of The Living Dead, the fact it takes place largely in a basement would look less like canny guerrilla filmmaking and more like staggering incompetence. It only took NASA eight years to put men on the moon from the point they started trying, which puts the value of many inhibited projects (like my folder of unfinished novels) into depressingly sharp relief.
Dead Island 2 does not put zombies on the moon, though given how daft the main game is, don’t rule out a Dead Island 2: Moon’s Haunted expansion shambling your way in late 2023. Yet that doesn’t mean it’s a bad game. In fact, it’s quite an enjoyable one. Together, Deep Silver and Dambuster Studios have raised a moderately entertaining sequel to Techland’s ye olde zombie survival sim, one that injects some life into its desiccated subject matter by being incredibly shiny, wilfully silly, spectacularly gory, and generally a touch more imaginative than I expected.
