Just watch New Zealander Goldfish's face as he plays Half-Life 2 using the Oculus Rift headset and Razer's Hydra motion controller to see how exciting the dawn of virtual reality gaming is going to be. Like most of the gamesplaying public, the YouTuber will be intimately familiar with the critically-adored FPS, but the simple act of moving and shooting in the modded version of the game makes him grin uncontrollably. Goldfish — presumably not his real name — beams as he aims the game's crossbow using its attached sight, hurls grenades over his shoulder while running, and reloads revolvers by flicking them open and tipping virtual bullets onto the floor.
