This social munzee is located in Second Life virtual world. If you would like to capture it, you have to register at www.secondlife.com (it's totally free), download the Second Life Viewer to your computer, log in, and then find the munzee inside this virtual space.
The munzee is located somewhere here: secondlife://Hippoden/92/132/27 (hint: "on the wall of the building").
You will probably have to zoom on the munzee! Press down ALT, move your mouse cursor on the object, press down ALT + LEFT mouse button, then move your mouse forward-backward to zoom in-out. Press ESC to zoom out (default view).
