Charybdis is a multiplayer VR sim where you race submersibles to capture the treasure and escape. You will navigate through an under sea maze to find you treasure and bring it to the surface. Watch out for monsters as well as other players. Charybdis is calling, will you pick up? My job on this project was retrofitting a Unity URP underwater shader to work with VR in Unity 6. It took me many many months but I eventually got it to work correctly and optimized it a bit.
