We found out during E3 that the Rupee system in The Legend of Zelda: Breath of the Wild will work slightly differently than they have in previous Zelda games. Eurogamer says that when they played the demo at the entertainment show you couldn’t find Rupees as normal by slicing grass and opening the variety of chests found in the environment. Plus there was no Rupee meter displayed on the screen. However French Nintendo site Nintendo Sphere found a lovely purple rupee on the ground near the body of an ancient Guardian enemy. You can check that out in the footage below.
