FAQ
- Is Immunity Protocol single-player only or does it have multiplayer?
- Immunity Protocol is strictly a single-player experience. There is no multiplayer or co-op mode of any kind. The game is designed around solo progression, where you build up your character's power through permanent Laboratory upgrades between runs. Each run is you alone against the horde, relying on your sentinel companion and carefully chosen weapon and passive loadout.
- How many weapons, sentinels, and symbiotes are available?
- The game features 27 weapons, 10 sentinels, 6 symbiotes, and 17 passive upgrades. Sentinels are autonomous combat companions with unique abilities that fight alongside you. Symbiotes attach to your character and grant passive bonuses or reactive effects. Experimenting with different combinations of these elements is essential for discovering powerful synergies and surviving deeper into the biomes.
- What are the system requirements for Immunity Protocol on PC?
- Minimum requirements are Windows 10 64-bit, a Core i5-4590 or FX-8350 CPU, 4GB RAM, a Vulkan-compatible GPU with 1GB VRAM, and 1GB storage.

- How does the Laboratory and blueprint banking progression work?
- The Laboratory serves as your hub between runs. While exploring the biomes you collect blueprints, which are automatically banked and persist even if you die.

This means every run contributes to your long-term power, making successive attempts progressively more manageable.
