From GameWatcher: “Rage 2 is out now, and it boasts a wide, expansive open-world full of dangers. To get by, you’ll need to upgrade your gear as quickly as possible, and to do that, you’ll need cash and Feltrite. The easiest ways to get these are in the game’s equivalent of loot chests – Rage 2 Storage Containers.”
