These hardpoints are essentially locations where specific structures can be placed. Hardpoints are being broken up into five different categories, and each Walker will have a base rig with a set amount of hardpoints available. Luckily, players can update the rig with specialized versions intended for specific tasks like hauling or fighting, and rigs will be part of the game’s loot system, making them findable and even tradeable.
