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.


Resin is a highly pliable Combine crafting material stored in capsules, solidifying when used to print objects in a Fabricator. Resin is extremely versatile, being able to take various shapes, and is a necessity in creating weapon upgrades. Therefore, collecting it is of great importance in-game. Alyx Vance makes extensive use of Resin and Fabricators to upgrade her weapons over the course of Half-Life: Alyx . To upgrade a weapon, she must first put a weapon into the cradle of a Combine Fabricator, then choose an upgrade she can afford on the screen. Once chosen, Alyx must then load the stacks of Resin pucks into the machine's deposit slots before the weapon is modified and dispensed back to the user.
