Ever wondered why we like killing zombies so much? It's because they exist in the center of a sweet spot, between recognizably human and monstrous and different enough that there are no moral ramifications. Shooting robots and demons is fine, but they're perhaps a little too abstract for us to understand the impact, the damage, of every hit. Games where you're killing people, it might be enjoyable, but a little voice remains at the back of your head, telling you to feel guilty. Zombies solve this problem. One of the best undead-slaying games of the last decade, alongside hits like Resident Evil, a true genre classic has finally shambled onto Steam, and it takes the thrill of the kill to stratospheric new levels.

If you're still not convinced, the sandbox game sold more than 2 million copies during its initial launch months, setting a new record for publisher Deep Silver. A new expansion has also just been released, and now – after a year-long exclusivity period on the Epic Games Store – Dead Island 2 is finally available on Steam, where you can buy the Standard, Deluxe, or Gold Editions, which all contain various additions and DLC. If you want to give it a shot (or a bash, or a swipe with a flaming katana) just head right here.
