Hitman 3 VR Move Controllers isn't needed to play the game in VR. All you need is the requisite PSVR headset. You don't use the Move Controllers at all, but you'll need a DualShock 4. Here's how to play Hitman 3 in VR.
Hitman 3 VR Move Controllers Not Needed for Play
If you have the game on PS5, you'll need the PS5 PSVR adapter to use your existing PlayStation camera on the new hardware. Luckily, you can score one for free from Sony if you can wait for shipping. You also won't be using the PS5's Dual Sense, as the camera needs to track the light bar on the DualShock 4. PS4 users need not worry.
You control most of Agent 47 with the normal control scheme, but you'll be aiming guns with the motion controls. As the light bar is the primary tracking method, aiming can feel wonky or inaccurate sometimes. That shouldn't keep you from playing, as Hitman 3 lets you play all of the World of Assassination trilogy in VR if you have the levels imported.
Hitman 3 VR is currently a PSVR exclusive, so we can expect a greater range of motion control if the game comes to the greater VR ecosystem for PC. For now, experience just needs the camera, headset and DualShock 4.
