Gun-hating Gizmodo is scared, they write:

Shooting a gun with Google Glass looks frighteningly like a video game

Here’s what it looks like to fire a weapon. Oh? You’re not impressed? Right. I understand. Because every first person shooter video game that kids play these days looks exactly like this. Hell, to be honest, the video games might look even more realistic than real life (if that makes any sense).

YouTube user cheekflapperer took Google Glass to the gun range and showed it firing various weapons. It’s frightening (and totally unsurprising) how much it looks like a video game.

Poor Gizmodo, I guess those Call of Duty geeks get scared when shooting a real gun. Pathetic.
