1Week

1Week is a single-player PvE survival sandbox set in a world without oxygen. You must find refuge underground before the apocalypse strikes, then rely on genetically modified plants and careful resource management to stay alive.

Explore and survive

Explore underground depths, discover new biomes and search for every species before it is too late. Procedurally generated maps and resource distribution shape each expedition, while a dynamic day-and-night cycle, character conditions and status effects affect your survival. Manage oxygen and breathable areas as you explore.

Build your shelter

Gather, mine and extract resources, then refine valuable materials and craft items at multiple workstations. Build and organize an underground shelter, developing a small refuge into a place that can protect you from dangers outside. Grow genetically modified plants, cook food and manage your supplies.

Fight underground threats

Use weapons and tools for combat, gathering and exploration. Fight zombies and other underground creatures, including those corrupted by hunger and isolation, and loot what you need to survive.
