In the next update for Ironwolf VR we will be adding an upgrade system. This will allow players to buy upgrades with credits they earn as they play in the open world. Our aim is for this system to make full use of VR, so rather than have a 2D UI to perform upgrades we’re basing the upgrade system around physically adding components to the submarine.
