Old School RuneScape in first person, with Dark and Darker's weapons at the Grand Exchange and extraction raids in every dungeon.
Play the real Old School RuneScape, the whole map with every dungeon and boss, from an eye-level first-person view, with Dark and Darker's weapons and raid rules mixed in. Everything from Dark and Darker is read from your own install.
Darker Armory at the Grand Exchange. Type "armory" or a Dark and Darker weapon name, like "Zweihander", into the GE buy search to see Dark and Darker's weapons: about 40 of them, each with its real icon, rarity and damage taken from your copy of Dark and Darker. Each one is a real OSRS weapon of the same kind, and once you own it, it shows as the Dark and Darker weapon in your inventory, your menus and your hands.
Raids in every dungeon. Go underground or into a boss lair and a Dark and Darker raid starts. A timer counts down, and everything you loot gets a rarity from Poor to Unique. After a few minutes an extraction portal opens at a nearby exit. Escape through it and your loot goes into your Darker Stash. Die, or get caught when the dark closes, and that raid's loot doesn't count. All loot is real OSRS items, so you can sell it at the Grand Exchange as usual.
Needs: Old School RuneScape and Dark and Darker installed. Runs through RuneLite, which it sets up for you. Jagex accounts link once through the Jagex Launcher. Single player.
