Is this game any good?
Its depends on what types of games you like. You can look at it like ARK with you having to survival an onslaught of enemies, but this time its zombies. You have to build your weapons, traps, and buildings up to the highest ability if you want to survive as long as possible
It's not bad, I have a few friends who have been addicted for years and have logged 3000+ hours vanilla. Mods can be a while new story. Similar to minecraft with eating and voxel based world, full of zombies that can be customized (slow, fast, more/less hordes). There's no real story so far, but it's slowly trickling in through updates, it's still alpha. The game is named for the waves you'll face every 7 days.
