The World War Z Aftermath next-gen update brings new visuals, fixes old audio issues, and introduces an expanded Horde Mode XL that packs more zekes on-screen than ever. The game is entirely predicated on the uninhibited good time that mowing down waves of onrushing enemies presents itself. Unfortunately, that's both where the game starts and ends. It's a rush, over and again, but when you want to look for something different, you have to go elsewhere to find it. A great gameplay loop to be sure, but a one-trick pony never the less.
