Can you simultaneously install Berserk and Sandevistan Cyberware in Cyberpunk 2077?
No, because Berserk, Sandevistan, and Cyberdeck are all Operating System Cyberware Implants. You can only have one type installed at a time. You can swap out V's Operating System at a Ripperdoc for a cost of Eddies to install the hardware. Moreover, the player can respec V's attribute and perks via the main character menu for a cost of Eurodollars. The higher V's level, the more expensive it is to respec.
