Sony is expected to show more of its virtual reality headset, called Project Morpheus, at E3. In fact, it made an appearance last night on The Tonight Show with Jimmy Fallon, which probably guarantees it'll play a big part in PlayStation's news conference on Monday.
Fallon, with the actor Channing Tatum, and Joshua Topolsky of Polygon's sibling site The Verge, show off what Topolsky says is the first two-player demonstration of Morpheus. (Skip ahead to 1:48 of the video to see the demo.)
The two grasp PlayStation Move controls and, like Moon-Watcher with the femur in 2001: A Space Odyssey, slowly realize how to use them as weapons. Fallon beats up a dummy suit of armor while Tatum tries to shoot Fallon with a crossbow. Then a dragon shows up and freaks out Fallon.
