The guide details the research tree in Graveyard Keeper 2, explaining which technologies players can unlock to expand and improve their graveyard and base. It focuses on Building and Smithing, while noting that other research categories require separate guides and must first be unlocked.

– Building research covers Wood, Stone and Clay technologies, including stockpiles, woodworking stations, quarries, mining, pottery and related perks.
– Smithing research includes furnaces, anvils, tools, weapons, steel production, engineering, casting and jewellery-making.
– Unlocks require red, green and blue research points, as well as materials, blueprints, character conversations and zombie-related tasks.
– Costs range from small early investments, such as 5 red and 5 green points, to advanced upgrades requiring hundreds of research points and rare resources.
