Research

Research is a feature in The Last Stand: Dead Zone that allows the player to upgrade and improve their compound and equipment.^[1] It is unlocked after completing the Research Bench.

Items[]

This section requires expansion. You can help The Last Stand Wiki by adding to it.

Special research items may be found while scavenging in the Dead Zone. They may consist of notes or components.

Research projects[]

Completed research project — A completed research project.

Projects are classified into six categories: Comfort, Equipment, Production, Security, Storage, and Traps. Each project has ten levels of research, which correspond to the ten upgrade levels on the Research Bench. For example, a Level 5 project would require a Level 5 Research Bench to complete. All research projects take 20 hours to complete, and cannot be cancelled or sped up once initiated.^[2]

The Research Bench cannot be upgraded if a project is currently underway, and projects cannot be initiated while the Research Bench is being upgraded.

The estimated time to complete all research projects is 18 months.^[2]
