Developer: The Fun Pimps

Genre: Survival horror

Theme: Man vs wilderness, man vs zombies

Live the post-apocalyptic dream in 7 Days to Die. The game takes place after the fall of civilization in a world that is entirely buildable and equally destructible, combining elements of exploration, scavenging, and base-defense.

The scariest thing in the picture is the lack of mittens

Each play session is unique in that the player's world is randomly generated, featuring expansive cites, mountains, caves, and other forms of wilderness. Scavenging is the key to success and players will need to search their environment to gather supplies for creating tools, weapons, defenses, and shelters.

Anything in the game can be destroyed and scarped for resources, even the terrain can be destroyed and mined. These resources are necessary for crafting tools, weapons, and homes for players.

Players can take this world on alone or with friends at their side to increase their chances of survival. With an ally at your side you can create sturdy shelters and defenses quickly and safely. Players can spend their time growing plants, hunting animals, developing skill trees to enhance abilities, and completing missions for NPCs in exchange for experience and items.

As 7 Days to Die is currently in its alpha stage, all of these features will be expanded upon in future developments, adding more depth and additional dangers.
