Immunity Protocol Character Collection Guide

Unlocking Characters in Immunity Protocol

Building a diverse roster of immune cell sentinels is essential for survival in the chaotic biosphere of Immunity Protocol. Each character offers a distinct playstyle, from aggressive frontline fighters to supportive tacticians. You start with a single default character, but the game provides multiple paths to expand your collection.

Most characters are unlocked by completing specific milestones during runs. For example, surviving a certain number of pathogen waves or defeating a particular elite enemy type will reward you with a new character token. Other characters are tied to progression systems like the upgrade tree or prestige levels. For a deeper look at how progression works, check out our progression system guide.

List of All Characters and Their Abilities

The current roster features a variety of immune cell classes, each with unique starting weapons and passive perks. Here is a breakdown of the key characters you can collect:

• Macrophage: A balanced starter class with a steady auto-firing weapon and a passive that increases health regeneration. Ideal for learning the game's mechanics.
• Neutrophil: A high-damage melee-focused class. Its weapon fires in short, powerful bursts, and it gains a speed boost after eliminating enemies.
• Dendritic Cell: A support class that marks enemies for bonus damage. It features a slower firing rate but grants team-wide buffs in co-op modes.
• Lymphocyte: A ranged glass cannon with piercing projectiles. Its passive ability increases critical hit chance against bosses.
• Memory Cell: A specialized class unlocked later in the game. It retains a percentage of upgrades between runs, making it powerful for farming resources.

How to Farm Character Tokens

Character tokens are the primary currency used to unlock new immune cell sentinels. You earn them through various in-game activities. The most reliable method is completing daily challenges, which reward a token upon first completion each day.

Another efficient strategy involves focusing on the early waves of a run. Certain elite enemies have a higher drop rate for tokens. Equipping gear that increases item find rarity can significantly boost your token acquisition. Refer to our farming guide for optimized routes and strategies.

Best Characters for Beginners

If you are new to Immunity Protocol, starting with the right character can make a huge difference. The Macrophage is the safest choice due to its balanced stats and self-healing passive. It allows you to focus on movement and positioning without worrying about constant damage.

Once you feel comfortable, try the Neutrophil. Its aggressive playstyle teaches you about enemy patterns and risk-reward positioning. Avoid the Lymphocyte until you have mastered dodging, as its low health pool can be punishing. For a complete overview of starting strategies, visit our beginner guide.

Advanced Collection Tips and Strategies

For veteran players, maximizing your character collection requires efficient run planning. Prioritize unlocking the Memory Cell early, as its persistence mechanic accelerates all future progression. Pair it with the prestige system to multiply your token gains.

Finally, keep an eye on event updates. Limited-time events often feature exclusive characters that cannot be obtained through standard gameplay. Check our event guide for the latest opportunities to expand your roster.
