On your waist you have a loot pouch which you release loot objects over to collect them (it's nothing fancy, the loot just disappears over the pouch), a book which when grabbed opens to show the menu options and notes you've found throughout the level (it's pretty nifty actually, you have to manually turn the pages), and keys you've found throughout the level. Enemy armor plays a role in the effectiveness of arrows but I didn't really test this because combat in Thief games isn't of much interest to me-unless perhaps if it has fully modeled melee combat physics like Blade & Sorcery. The "feel" of the bow and the arrow physics aren't bad but they're also not great (vs e.g. Your bow is over your left shoulder and you can see each type of arrow in your possession above your head-you just reach up and grab the bow with one hand (don't necessarily have to look as it's in its natural position) and the desired type of arrow with the other hand, insert the arrow into the bow, draw the bow back, and then aim and release (as you would expect with the motion controllers). You will tire (as indicated by heavy breathing) and fall if you're in a climbing state for too long. To climb you just hold in the grip buttons on the controller at any point on the wall and then pull yourself up the wall one hand at a time (your body translates relative to the grip point)-standard "Climbey" climb mechanics. crates), which is indicated by your hands turning blue and your motion controllers vibrating when your hands come into contact with the wall. (there is an option to toggle crouching via a button as well) You can climb most types of walls or objects (e.g. You can even go fully prone (on your actual floor) and crawl under a bed if you want. You use the joystick on one of the motion controllers to move (they also have "run in place" locomotion but that's not my idea of a good time) and you stand/crouch by doing so in real life, which affects your movement speed and how visible/noisy you are. With respect to visibility and sound, a yellow or blue icon will show up at the bottom of your vision when you are visible or when you are making making noise, respectively.
Here are the basic mechanics: You have a bow with 3 types of arrows (combat, water, and noise arrows) and a "wrist dagger" that lets you execute enemies by stabbing them in the back of the head (but no bludgeon). So to start with you're kind of just given a basic tutorial and then dropped into the first of two "dungeon" themed levels (basically just lots of stone hallways).
I've described things somewhat thoroughly below because I know many of you don't have a VR system. Of course it is early access so this is not entirely unusual and I wasn't really expecting much more than that anyways. It feels more like "Thief VR tech demo" or proof of concept-at least at this point. I can't really say much about the game on its own merits because, well, there isn't too much there and I can't really tell if there's an actual story. Played this a while back on an Oculus Rift but didn't end up doing a write up until now so my impressions may be a bit out of date.
