Resin is an advanced form of building material first featured in Half-Life: Alyx. They are found in the form of "pucks" throughout the game and used in the weapon upgrading system.
To upgrade a weapon, the user must first put a weapon into the cradle of a Combine Fabricator, then choose an upgrade they can afford on the screen. Once chosen, the user must load the Resin pucks into the machine's deposit slots before the weapon is modified and dispensed back to the user. Resin seems to be a pliable form of Combine metal while in its capsule, until it is turned solid when used in a fabricator. Resin is extremely useful for its necessity in creating weapon upgrades, and therefore collection of it is of great importance. Alyx Vance makes extensive use of Resin and Fabricators to upgrade her weapons over the course of Half-Life: Alyx .
