I just downloaded this and tried it out today and ... WOW! For a free experience, it is awesome! Some may not like it because it's not sweet, cutesy or upbeat like most of the other experiences in the oculus store, but that's what makes it so realistic and good, IMHO! (The sergeant reminded me of some bosses I've had!)
When I first glanced at the description, I thought it was about miners, but since it was free and looked good, I didn't bother reading it more carefully. Imagine my surprise when I discovered it makes you a soldier on the battlefield trenches in World War I! This was edgy and raw, and really gives you a feel of what is is like in this historic but dark period in world events.
When you start start out in the shack at the beginning, you can see the battlefield through the cracks in the woodwork. The textures are great, and the uneven wood slatting of the underground tunnel is so realistic!
I like historic experiences like this, because it gives puts you in a time period that most of us will otherwise never have a chance to experience. There are some glitches and the character animation is not perfect, but I know how difficult it is to do this totally convincingly and we are still in the relatively early days of virtual reality.
My grandmother gave me a beat up old book that had been kicked around in her basement for decades, Colliers new photographic history of the World War (published in 1919), and I can tell you, World War I was truly hell, and I think this VR experience captures it effectively.
I highly recommend it, but expect it to be a somewhat depressing experience.
