The game uses an overhead perspective for exploration across a large post-apocalyptic world. The party travels between ruined locations, searches buildings, collects food and equipment, and encounters mutants and other hazards.

Combat is turn-based and emphasizes choosing suitable weapons and managing the condition of the party. Progress depends on finding supplies, learning which objects are useful, recruiting or preserving party members, and discovering enough information to reach the game's ultimate objective.

Search every accessible structure and keep a varied supply of food, weapons, and equipment. Do not assume that an unfamiliar object is worthless; scavenged items can be important for survival or progression.

Conserve resources, avoid unnecessary fights, and record useful discoveries. Exploration and experimentation are essential because the game provides limited guidance about its world and objectives.
