• Features a realistic cycle of night and day, making the zombies slow during the day, yet faster and more aggressive during nighttime.
• Zombies featured in this game are not just the normal ones they will run, climb, dig, destroy doors, walls, or even entire buildings, if necessary, just to get to the player and eat them.

Reviews

There’s a hint of a good game in 7 Days to Die’s mix of zombie attack preparedness and crafting and cooperative stands against zombies, and it has valuable ideas to contribute to the genre. In fact, you can almost hear them screaming to escape from beneath terrible graphics, barely useable menu controls, and shoddy console optimization. This is an apocalypse amongst apocalypses.

IGN  

7 Days to Die on console is a terrible port of a game which otherwise shows real promise on PC, where it currently languishes in Early Access. In its current state on consoles, the game is technically playable, but that’s the best that can be said of it.
