Ultimate Outbreak Zombies Tips & Tricks Guide (Cold War Zombies)

Outbreak Zombies mode is a unique experience, differing from the regular round-based mode, and instead offers a new difficulty level. The new open-world game mode has paved a fresh path with endless possibilities for the future of Call of Duty: Zombies.

To put things into perspective, in regular Zombies, you will start to feel the difficulty rising on round 25+. In Outbreak, you will already start feeling the challenge at around difficulty level 7-8. The new mode features three regions: Ruka, Alpine & Golova, the first two being Fireteam: Dirty Bomb maps, while the latter is a new region specific to Outbreak. You complete the main objectives in each region to then either warp to the next region or exfil. Warping to the next region increases your difficulty level by 1.

After playing Outbreak for a few weeks, we have some extremely important tips and tricks that will elevate your gameplay to a whole new level and help you progress further with ease. Here are our best tips and tricks (in no particular order) that will help you survive the new Outbreak Zombies mode effectively.

Best Weapon Loadout

Ever since the introduction of custom class loadouts in Zombies, you can now jump in with your favorite weapons and attachments. It would be best if you modified your weapons to have the maximum possible damage, and then later in-game, you can upgrade the tier of your weapon in combination with Pack-A-Punch, increasing its effectiveness even further.


No matter what Zombies mode you play, the one weapon dominating the current meta is the Hauer 77 shotgun. This weapon does extreme damage, and as you progress through the rounds/difficulty levels, you can upgrade it into a true killing machine.

When it comes to weapon upgrades, it's important to keep track of how much Salvage you have - without Salvage, you cannot upgrade your weapon rarity or armor.

You can choose attachments that can maximize or increase the rate of salvage drop from the zombies. The following is our recommended Hauer 77 loadout for any zombies mode.

The loadout focuses on maximum effective damage and an increased rate of salvage drop.

  • Muzzle: Flash Cone 12 GA
  • Barrel: 25.2" Task Force
  • Body: Ember Sighting Point
  • Magazine: STANAG 8 Rnd Tube
  • Stock: Marathon Pad

The Flash Cone 12 GA muzzle attachment increases your equipment drop rate, and there are no drawbacks associated with this attachment. The 25.2" Task Force barrel attachment is the most important as this increases your overall damage. It sometimes shows the damage increase as +50%, and sometimes it shows +500%. This is seemingly caused by a bug, and regardless of what it shows it significantly increases your weapon damage.

The Ember Sighting Point body attachment increases your salvage drop rate and increases hip-fire accuracy by 30%. You must choose the STANAG 8 Rnd Tube as your magazine attachment as it is not a pretty sight when you are overwhelmed with a horde of hundreds of zombies. You need all the ammo you can get. Finally, the Marathon Pad stock attachment helps with the mobility aspect of your loadout. It helps increase sprinting speed, shooting move speed, sprint to fire time, and aim walking movement speed.

This is especially important when you train up a horde of zombies and shoot them while moving backward - and if you have the Stamin-Up perk, then you can move backward even faster. This should be your ideal Zombies loadout, no matter which game mode or map you're playing.

Complete Side Objectives

As mentioned before, there are primary and side objectives in each region. You can directly go for the main objectives and complete them to either advance to the next region or exfil. However, if you do it like that, you will notice the difficulty level shooting up for you because you didn't prepare for the later rounds.

You can be prepared for the later rounds by utilizing the ease of the early rounds. It is not necessary to directly do the main objectives and move on to the next region. We highly recommend you do all the side objectives in each region you visit until difficulty level 5-6. This will help you set up for the later rounds, upgrade your weapon, and get all the perks.

The following are the side objectives you can do:

  • Locked Golden Loot Chest: If you look at your mini-map, this icon appears to have a lightning bolt with a cloud. When you go to the marked location, a huge lightning bolt strikes down, spawning a golden chest. This chest is locked at first but can be opened by 'confronting the Dark Aether.'

    You can interact with the chest, and doing so will spawn many regular and elite zombies. You must eliminate all the zombies spawned in by the golden loot chest for it to be unlocked. Once you kill the last zombie spawned in by the box, it will unlock.

    You can then open the box to get valuable rewards such as high-tier weapons, salvage, equipment, and even a free random perk. This side mission is a great way to get free perks early in the game. You can do these side missions as early as difficulty level/round 1.

  • Feed The Dragon: To find this side objective, you must look for a dragon's head icon on your map overview. When you go to the marked location, you will find a huge machine with two canisters on either side of the machine.

    You can activate the machine for 500 points, creating a ring of fire around the machine with a dragon's head popping out of the top.

    A number of zombies will spawn all around you in a circle and charge at you. You must kill these zombies within the ring of fire for them to be fed to the dragon. When a regular zombie enters the ring of fire space, they start to glow purple. When they do, you can kill them, and they start floating up to the dragon's head to be devoured by him.

    Once the dragon has been fed enough zombies, the ring of fire disappears, and the dragon machine flies up to the Dark Aether portal, leaving behind a loot chest that you can open for exciting rewards such as high-tier weapons, salvage, equipment, a free random perk, and even a wonder weapon. The rarity of the rewards increases depending on how many zombies you kill - the more you kill, the better the rewards.

  • High-Value Target: This side objective is indicated with a set of three skull icons on the map overview. When you go to the marked location, you will find a bunch of dead soldiers, and one of the dead soldiers will have a radio that you can interact with to play a message.

    Once the recording ends, a beam of blue lightning will shine down at a distance, spawning a bunch of elite zombies.

    You must kill these zombies to complete this side objective. There is high potential for either a free random perk or a wonder weapon drop when you kill one of the elite zombies.

These side objectives are a great way of earning points and getting free perks, equipment, salvage, and potentially a wonder weapon. Although the wonder weapon has a higher probability of dropping at high difficulty levels, you can still get the other goodies early in the game at lower rounds. This helps you save up salvage and points to upgrade your weapon rarity and pack-a-punch, respectively.

Buy Perks In Correct Order

You should buy perks in a specific order so that if you go down, you lose the perks you don't feel are super valuable or helpful. You always lose the perks that you buy last first, and then it goes back from there.

It is highly recommended that you always buy the important perks first, such as the Jugger-Nog perk, Stamin-Up, Speed Cola, and Quick Revive. If you're a console player, then Deadshot Daquiri as well since it helps lock onto the head easily. The rest of the perks, such as the Elemental Pop and Tombstone Soda, aren't as important as the previously mentioned perks.

Let's say you bought the perks in the following order: Jugger-Nog, Stamin-Up, Speed Cola, Elemental Pop, and Tombstone Soda. If you go down, you will first lose Tombstone Soda, then Elemental Pop, and then the Speed Cola perk. So, be careful when buying your perks and be smart about it, especially at higher difficulty levels.

Zombies & Their Ammo Mod Weaknesses

It is also worth knowing what ammo mods are effective against what zombie as it can make a huge difference in the time it takes to kill them. The following table shows you the list of zombies and what ammo mods are effective against them.

Zombies Ammo Mods
Megaton Dead Wire
Mangler Napalm Burst
Mimic Brain Rot
Krasny Soldat Shatter Blast
Tempest Brain Rot
Plague Hound Napalm Burst
Hell Hound Cryofreeze

But which ammo mod is the best overall? The best ammo mod to use is Dead Wire, especially when upgraded to tier V. Dead Wire wasn't as effective or useful before the release of Outbreak and two extra tiers of upgrades. When you upgrade the ammo mod to tier V, it becomes exceedingly powerful and can one-hit kill the zombies even above round 50.

The fifth tier is a game-changer as it helps spread the electricity from the Dead Wire mod to the surrounding zombies, stunning them and ultimately killing them. This is useful when taking out a horde of zombies. You can train several zombies and then time your shots to stun one zombie that, in return, will spread the electricity to the rest of the zombies in the horde, killing them all.

Dead Wire also comes in handy when dealing with Tempest in the Outbreak mode. Tempest is a fast mini-boss and always teleports after getting hit a couple of times. You can take them out fairly quickly at lower difficulty levels, but it takes quite a beating before finally going down at higher rounds.

When incurring major damage, Tempest keeps teleporting, but with a fully upgraded Dead Wire mod you have a good chance to stun them, keeping them in place. This is possible thanks to the tier IV Dead Wire mod upgrade that allows you to stun special enemies (elite zombies or mini-bosses).

Transferring Canisters Effectively

This is an objective-specific tip that can help you a bunch when transferring canisters. During the 'Retrieve' primary objective, you are tasked with retrieving two Aetherium harvesting canisters. You must carry them manually to a set of rockets and install them so they can be flown away from the site. When you carry these canisters, you move slower than usual and can't use any of your weapons or equipment.

You can do two things to make canister carrying easier for yourself - using vehicles or using the Aether Shroud Field Upgrade.

  • Vehicles: Yes, you can carry the canister and then hop on a vehicle to bring it back to the rockets. However, due to the sheer amount of energy produced from the canisters, vehicle health gradually decreases. It would be best if you had a vehicle nearby before carrying the canister.

    On top of the gradually decreasing vehicle health, when you are carrying canisters, many regular and elite zombies spawn, including Tempest. You need to absolutely avoid Tempest when using a vehicle as one hit from them will cause your vehicle to stall due to an EMP attack.

    It is best to ensure there are two vehicles nearby, one for each canister, as by the time you reach the rockets carrying one canister, the health of the vehicle would be below 50%.

  • Aether Shroud: The Aether Shroud Field Upgrade is beneficial when carrying the crystals, especially when it is upgraded to Tier IV and V. Upgrading to at least Tier IV allows you to move much faster when shrouded and upgrading to Tier V allows you to hold a maximum of 2 Aether Shroud charges.

    You need to activate Aether Shroud before picking up the canister. Otherwise, you won't be able to activate it when you've picked up the canister as you get a limited-time field upgrade from the canister itself that creates an "aether" explosion killing all the zombies around you.

    With the Aether Shroud activated, the zombies will ignore you for a limited time period allowing you to move freely. Thanks to the Tier IV upgrade, you can move faster, as carrying the canister slows you down. The Aether Shroud Field Upgrade also comes in handy when you are inserting the canister into the rocket. You should insert it while you're shrouded, as no zombies can attack you while doing so.

Unlimited Death Machine Ammo

Everyone knows that the Chopper Gunner has been one of the best Scorestreaks in Zombies, and while it is still among the best, the benefits have diminished in Outbreak. There are several reasons for that; the Chopper Gunner is not applicable when activated during primary objectives such as 'Holdout'; even during the Specimen Analyzer primary objective when the analyzer is inside the building, such as the Church in the Golova region or the lodge/cabin in the Ruka region.

This renders Chopper Gunner less than ideal. Another issue with the Chopper Gunner Scorestreak is that there are many buildings in each region. Whenever you activate the Scorestreak, the zombies take shelter in these buildings, making it a bit of a waste.

Yes, one may argue that you can use a Cymbal Monkey to attract them to a single location and activate the Scorestreak, but that is only applicable at lower difficulty levels. As you progress through the rounds and reach higher difficulty levels, the zombies become "super sprinters." The amount of time it takes for you to charge up the Cymbal Monkey and throw is too slow for it to be practical at higher rounds.

The best new Scorestreak perfect for the Outbreak mode is Death Machine. This Scorestreak absolutely annihilates zombies, and the best part about it is that you don't have to get that "aerial view" when using it. You can simply switch between your Scorestreak and regular weapons to save Death Machine ammo for whenever you need to use it next. You can use this Scorestreak outdoors and indoors alike. You have no restrictions except the limited ammo (400 rounds).

You can also buy this Scorestreak from the crafting table for 100 High-Grade Salvage.

Now we come to the main point, which is the unlimited Death Machine ammo - to get unlimited Death Machine ammo, you must have at least 1 shot left.

If you use it all, you will lose the Scorestreak and will need to repurchase it. When you have 1 ammo left, you can warp to the next region, and you will notice that your ammo has been replenished back to 400 rounds.

You can do this as many times as you want. All you need to do is ensure you have at least 1 ammo and warp to the next region.

Switch Field Upgrades

If you didn't already know, you can switch out your field upgrades mid-game. You can set up different load-outs with different field upgrades and switch to the loadout to change your field upgrade only. Your weapon won't change.

Note that once you change your loadout, the swapped field upgrade won't be charged and will start at 0. You'll need to kill zombies to charge it back up as you normally would. Check your equipped field upgrade's charge before swapping. If it is already full, utilize it before switching or it'll go to waste.

This comes in handy when you are going for certain objectives. For instance, if you didn't have the Aether Shroud field upgrade before starting the 'Retrieve' objective, you can switch to it before starting - we've outlined its importance further up. So, switch your field upgrades wisely depending on what primary objective you're working on.

Rule of thumb, Aether Shroud is good for primary objectives such as 'Retrieve' and 'Holdout.' In our opinion, Aether Shroud is the best Field Upgrade considering how difficult the 'Holdout' objective can get, let alone the overall gameplay at higher difficulty level.

Use Self-Revive To Your Advantage

Self-Revive is certainly there to save your life, but it can be even more beneficial when you are doing the 'Holdout' primary objective. The 'Holdout' objective is a time-based objective where you survive until the timer has run out. If you have a Self-Revive kit, you will be downed.

If you have a minute or so left on the timer, you can go down by timing it correctly and wait until the timer runs out. As soon as the timer touches 0:00 seconds, you will automatically be revived. This is highly useful at later rounds when you want to pass the remaining few seconds, as when you're downed, the zombies do not attack you.

If you have the Tombstone Soda Perk upgraded to Tier II, then the downed duration increases to 60 seconds. That is a whole minute, and you can definitely pass that time if you have 50-60 seconds left on the timer. If your tombstone soda perk is not upgraded to Tier II, your downed duration is 30 seconds only, so make sure you know the time and go down accordingly.

Remember, you do not have to revive yourself. You can save your Self-Revive kit when you absolutely need it in other critical scenarios. Either save your Self-Revive Kit or buy it from the crafting table for a whopping 250 High-Grade Salvage.

Jump On Objects

Here's another 'Holdout' objective tip which many of the players are not aware of. You must always be prepared for this particular objective as you get to higher difficulty levels. The confined spaces in these objectives make it very difficult to counter the hordes of zombies and elite zombies at later rounds.

You must take advantage of everything at your disposal to ensure you survive during the holdout and pass the timer no matter what. During the holdout objectives, you can mantle over or jump on objects to gain elevation where zombies cannot hit you.

Although, it doesn't last for long as the zombies start throwing their meat towards you. And, if there are a lot of zombies, the meat thrown at you from multiple of them at a time can cause some serious damage!

This is a good tip as it can help you quickly jump over an object that makes the zombies stop attacking you for about 7-8 seconds before they finally start throwing their meat at you. It's a good quick breather when surviving at higher rounds.

Here are some of the locations during the holdout objectives where you can jump on elevated objects.

  • Ruka: You can open the door upstairs and climb it to avoid getting attacked by the zombies, but briefly.

  • Golova: The Golova holdout location is the most difficult one out of all three regions, especially on higher rounds. It is best to know that you can climb the cabinet and wardrobe/shelf located inside the rooms at either end of the house you get stuck in.

    You must go to the side of the cabinet and jump on it to mantle up. You cannot climb it head-on from the front end.

  • Alpine: The Bathhouse location in the Alpine region is the easiest as you can run in circles around the Bathhouse and eliminate the zombies. You can still climb the shelves resting by the supporting pillars. First, jump on the nearest bathtub, then face towards the shelf, and jump over it. You will mantle right on it.

Free Points (Aetherial Orbs)

A mini side-easter egg rewards you with many points early in the game without fighting any zombies. This is done by finding the Aethereal Orbs that spawn in a set number of locations in each region. The Aethereal Orb only spawns in one of the spawn locations in each region, and the order of spawn is completely random.

The Aethereal Orbs are not indicated on the map until or unless you are in the vicinity of the orb. You must be near the orb for it to pop up on your mini-map. When you continuously shoot the orb, it drops a lot of essence (points) and eventually starts flying away to another location.

You must follow it until it stops at another location and shoot it again to drop more points. After the second time, the orb once again flies away to the third and final location, where it explodes and disappears, leaving behind valuable loot such as points, Scorestreaks, and high-tier weapons.

Feel free to check out our full guide on where to find these Aethereal Orbs in all the regions.

Mimic Loot Chest

It is never a pretty sight whenever you approach a large loot chest, and it transforms into a Mimic, giving you a haunting scare. You can avoid that very easily though - it is possible to differentiate between a Mimic disguised as a loot chest and a genuine loot chest using your 'Ping' feature.

When you ping a genuine loot chest, it will be marked on the screen as a loot chest.

But, if you try to mark a loot chest that is, in fact, a Mimic, it will not get marked. This is how you can differentiate between a Mimic and a real loot chest.
