Forget Niko, Liberty City itself is the true star of GTA IV. Rockstar has packed the city with enough tiny details to keep us playing and discovering for years. And man oh man were we thrilled to find this haunted playground near the first safe house. How is it haunted, you ask? The swing sets have chains hanging from them that, when properly nudged with a vehicle, will fling you violently up, down or sideways. Check the video for shocking proof. We’re not sure if this is a glitch or an easter egg left by an insouciant programmer. Either way, its hecka fun to see how far you and your car can actually be tossed by the vengeful swing set. If you’re thinking of trying it out yourself, we recommend multiplayer for the most dramatic effect. In single player, the force of the impact tends to throw you out of the car but multiplayer will let you soar high into the sky.
