This Protobuffer upgrade creates a pair of connected purple 5G portals that teleports any players between them, offering unparalleled mobility. By shooting a portal at your feet, you can additionally randomly teleport away to avoid danger or reposition strategically. It also grants passive movement speed, unlimited sprint, and the ability to fire while sprinting, making it ideal for players who prioritize speed and mobility over raw damage. Retaining all the core features of the base Protobuffer, this upgrade excels in solo play and speedrunning, allowing you to outmaneuver zombies with ease while maintaining full control over your strategy.
