Dying Light 2 is an action role-playing game from Techland and it's the sequel to 2015's Dying Light. In this game, you play as Aiden and you find yourself getting tangled up in the problems of The City. This settlement is one of the last human ones in a world where the Harran Virus runs rampant. While you are trying to figure out your own quest, you unwillingly get caught up in conflicts between the remaining humans.

If you are reading this guide, you are probably well aware of Aiden's problem and why his biomarker is so important. If you are not, then we strongly recommend coming back to this article after you get his biomarker in Old Villedor.

In this guide, we're going to explain more about immunity, how to track it, how to increase it, and what can affect it. Maintaining Aiden's immunity is the only thing that's helping him to stay human.

What Is Immunity

Immunity is the in-game measurement of how long you have until you succumb to your infection. Once you get your Biomarker with Hakon, you will be able to track and manage your immunity. If you let it run too low, you will succumb to your infection and die. Then, you will be reset to the nearest checkpoint or safe zone.

How to Track Your Immunity

There are two ways you can track your immunity in the game. The first one is, of course, the Biomarker on your wrist. As you are climbing buildings or performing actions in The City, your wrist will almost always be in view. There are several green bars on your biomarker. Each time you lose a bar, it will turn red. Once your biomarker is half red and half green, you should think about boosting your immunity quickly.

The other way to track your immunity is almost constantly on your screen. At the top of your screen in the middle. During the day, you will notice that the immunity tracker will decrease quite slowly as long as you are in the light. This is because the infection can be fought with UV light. However, your problems will begin if you spend too long in the dark and at night. During the night cycle, your immunity will rapidly decline. Once it gets very low, the icon at the top of the screen will warn you and it will show you how long you have left before it gets too low.

How to Increase Immunity

Luckily, there are quite a few ways that you can increase your immunity. Many of them are consumables that you can craft or collect as you venture around The City. We recommend collecting any of these consumables (or the materials to craft them) when you see them.

Immunity Boosters

Immunity boosters look a lot like modern-day inhalers. They are slightly rare to come across but you can find them in GRE crates or crates where you've had to pick the lock. Also, if you enter a high-rank area of the map, there is a good chance they are there. Different rank immunity boosters will be different strengths. A unique consumable booster can boost your immunity by 80% but an uncommon consumable may only boost it 35%.

If you cannot find any immunity boosters on the map, you can craft them with the following materials:

  • x2 Chamomile
  • x2 UV Shrooms

You must learn the blueprint to be able to craft them. You can purchase the blueprint from craftmasters or discover it around mid-way through exploring Old Villedor.

UV Shrooms

Time to go against all of your natural instincts and eat blue mushrooms that glow. UV Shrooms, as the name suggests, have absorbed a huge amount of UV Light. If you eat these, they will restore about 1/3 of your immunity.

UV Light Spots

If your immunity is running low and you think you can make it to one, running to the nearest UV spot will instantly recharge it. If your immunity is running down, the compass at the top of your screen can show you where the nearest UV Light spot is. It will be marked by a purple sun icon. The more you unlock windmills and safe zones, the more UV Light spots there will be.

If you're aware of your immunity, then you are probably aware that inhibitors are extremely important. Use your GRE key to access hidden GRE crates to collect them. Once you have three inhibitors, you can upgrade your health or stamina. Each time you increase either of these things, your immunity will automatically increase too. This means that you will be able to stay out at night and in dark areas for a longer period of time.

What Affects Immunity?

There are quite a few things in the game that will negatively affect your immunity.

The Dark: Dark areas can reduce immunity quickly. If they cannot be avoided (such as a mission scenario), then make sure you have enough consumables on you to get out of there safely.

Night: Nighttime is playtime for the infected as there is little UV light around. This also means that your immunity is lowered and will decrease much faster. This is why we recommend unlocking as many windmills and safe zones as you can. Doing this will give you more places to run to if your immunity is running out.

THV Chemical Areas: These are places on the map that are rich in the chemicals that were dropped on The City a long time ago. You cannot traverse through these, your immunity will almost instantly disappear. It's best to avoid them. They're easy to spot as the area is covered in a radioactive yellow hue and a warning should appear on your screen if you get too close.

Managing your immunity is just one of the things you need to do in Dying Light 2. You also need to watch your back for angry faction members and vicious infected. Check out our weapons list to learn which weapons you will have to help you survive The City and how you can get your hands on them. Also, we have a guide that shows you all of the monsters in the game so you can prepare yourself for the creatures behind the creepy noises in the dark.
