This post will cover Contagion build in Cyberpunk 2077. It is a quickhack that poisons enemies and spreads around. This build is especially deadly to groups of enemies.

This is a variation of netrunner build, so you can expect many things to overlap.

Contagion Build

This build concentrates on using quickhacks that spread around groups of enemies. As you can expect you will be weak against direct enemy encounters.

To counter this weakness we will invest heavily into quickhacks and stealth

Not only that but Contagion Build will also be able to craft the Legendary tier quickhacks for the maximum amount of damage.

Attributes

This section will go through recommended attributes and how you should progress with them. Picking the correct ones will ensure that you have sufficient stats to kill enemies.

Starting the game

For Contagion build, you want to start with a maximum allocation of Intelligence. This way your quickhacks will be the most effective early in the game

  • Intelligence+3
  • Cool +3
  • Body +1

Progression

Here is how you should have allocated the attributes to reach the core of the build

Level Reflex Body Tech Cool Int
10 3 5 3 8 12
30 3 5 3 20 20
  • Intelligence 20. Ensures that Contagion build deals the largest possible damage
  • Cool 20. You will get some great perks from this attribute that increases the effectiveness of quickhacks and stealth

Of course, this leaves plenty of points to be spent elsewhere. I recommend three options, that you can put the rest of the 20 attributes:

  • Technical Ability - for crafting quickhack components and legendary armors
  • Reflexes - will maximize the critical chance and improves monowire, blades, rifles, and handguns (I personally prefer this one)
  • Body - can use it to maximize survivability, and increase effectiveness with shotguns and blunt weapons.

Perks

In this section, I will go through recommended perks for the Contagion build in Cyberpunk 2077

Breach Protocol

This perk tree will improve your daemons and provide bonuses to access points. They will be important for collecting quichack components

16 Hasty Retreat Boosts movement speed by 50% when detected by enemies.
18 Critical Antidote Seems like this is the only perk related to poison that works together with Contagion

Build tactics

The build relies on having appropriate quickhacks. I recommend having these:

Contagion build quickhacks cyberpunk 2077

  • Contagion - spreads around a group of enemies dealing chemical damage
  • Short Circuit - very effective against drones and other non-human enemies
  • Ping - reveals all enemies connected to a network
  • Overheat - effective against human enemies

Another important aspect is to have Operating System - Cyberdeck. You want to have ones that spread the quickhack effect onto multiple enemies.

Some gameplay tactics

  1. When initiating combat I suggest first using Breach Protocol to get passive benefits and weaken enemies in the network. Once that is done the encounter will be much easier and quickhacks will cost less ram.
  2. Use Ping to reveal all the enemies in the Network to grasp the situation of how much you are outnumbered
  3. Now you are ready to start combat. If there are any drones, robots, etc. Use Short Circuit to shred them instantly
  4. Use Contagion on human enemies and see how the poison starts to spread around enemies. Slowly they will start looking for you.
  5. Hide somewhere so that enemies would find it difficult to see you or would take a long time to reach.
  6. It should take a few seconds and you can use the second Contagion or Overheat against a stronger enemy

Basic tips

  • Another good tip is to always carry some grenades. They can help you in difficult situations when enemies may reach you in close-quarter combat
  • Because the Contagion build has low HP always have some Bounce Backs.

Equipment recommendations

This section will cover how to best optimize Contagion build gear. I will go through the main gear that you should use to maximize the build's effectiveness

Weapons

The Contagion build does not rely on ranged weapons. However, you should still have them ready in case enemies get close to you or you are on cooldown. I only recommend Tech weapons as they can charge up and shoot through walls.

Priority Item Description
1 widow maker cyberpunk 2077Widow Maker This is the option that I recommend the most. It deals decent damage and has a good range and fire rate.
2 nekomata cyberpunk 2077Nekomata A Tech sniper rifle can be found very early in the game.
3 lizzie cyberpunk 2077Lizzie
An iconic pistol that releases extra rounds per shot. This makes it very deadly even as a pistol.
4 Db-2-satara-cyberpunk-2077DB-2 Satara
A Tech shotgun may not be the best option but it is very fun to use. It also provides good sound feedback making it very satisfying to use.
