After donning the Rift headset and going through a brief tutorial, I got the hang of using the Touch controllers fairly quickly. I picked two guns as my weapons of choice and wielded one in each hand. As you do so, the tutorial offers a brief hologram on how to reload your gun -- which either means lowering your gun and lifting it again or flipping your wrist to cock a virtual barrel. You'll know when to reload when the floating ammo digits above your gun is, well, zero.
In my demo, I was thrown into enemy combat fairly quickly, in what appears to be a storage facility. Thankfully, the bandits didn't appear to be terribly bright, and I could crouch behind barricades and walls without being detected. To move throughout the space, you simply aim your gaze at a pre-determined area -- they're highlighted in blue or yellow -- and press the A button. You'll be teleported there instantly. Blue spots have high cover but terrible shooting angles while yellow areas have low cover but you get to blast bandits with greater accuracy. After you clear the room of bandits, you get to move to the next stage by teleporting to the elevator and going on to the next floor.
Arktika.1 is what I would describe as a full-body VR game, as I not only used my arms and hands to shoot, I also bent down and got on the floor to avoid getting shot. It was a lot of fun, so much so that my 20-minute demo time flew by. The use of the Touch controllers really makes this game pretty immersive as well. Arktika.1 should be out by Q2 of next year, which is good, because the Touch should be available by then too.
