PlayStation VR Aim Controller
PlayStation®Camera (sold separately) required for PlayStation®VR and PlayStation®VR Aim Controller functionality.
it is worth buying but i do not know about gun club vr game
i bought one and they told me there was no warranty available because the item is listed as an accessory instead of a controller. Which is weird to me because it says aim controller right on the box
Unfortunately, this controller does require both hands. A VR wand might work for your son.
Yes, all the buttons are centered.
No, just games designed for it. You can use it to control the ps menu.
