Call of Duty: Modern Warfare 3 Zombies: how to complete Bad Signal

By Jesse Lennox December 13, 2023

Once Season 1 hit in Call of Duty: Modern Warfare 3’s Zombies mode, a new Act was added for players to dive back into the undead masses to complete more missions. Since this Act takes place after all the prior ones, it’s only natural that it puts players to the test.

The first mission in Act 4 is Bad Signal, which brings you to a new area that is more deadly than even the highest threat-level zones. If you’re struggling to survive this mission, we’ll give you clear instructions on how to complete Bad Signal.

Once you’ve selected the Bad Signal mission in the main menu and dropped into the game, you will have a special symbol placed on your map. Take note of it and make your way toward it. When you arrive, you will see that you have been led to a rift you can interact with. If you’re on a squad, a vote will trigger that needs to pass to start the real mission.

This rift transports you to the brand new Dark Aether zone, where your objective is to activate and fill four seals around the area. You fill them by killing enough zombies near them to fill up their respective meters.

The seals will be marked on your HUD and appear like small stone spires on pedestals. One of your squad mates must interact with it to activate it and create a ring of fire around it. This ring is the zone you must kill zombies within in order for them to count towards filling up the meter that will eventually break this seal. Because the zombies in this area are so strong, we highly recommend sticking together and doing each seal one at a time rather than splitting up and attempting to activate and destroy multiple at once.

Once you’ve filled all four, your goal will be to leave the Dark Aether; however, that doesn’t go according to plan. As soon as you approach the exit portal Gorm’gant, a giant boss worm will spawn that you need to take out. You’ll notice purple spots all around its tube-like body. Focus fire on those spots to damage it and keep your distance to avoid damage. Once you kill it, the mission will be complete.

2023 set an incredibly high bar for video game sequels

It's not an overstatements to say that 2023 was one of the best years for video game sequels ever.

Simply looking at The Game Awards 2023’s Game of the Year nominations, all of which are titles from preexisting series, proves that. It’s not just that we received a lot of new video game sequels in 2023; that happens every year. No, what makes the game sequels of 2023 stand out is how many of them impressively build upon what came before. From Marvel’s Spider-Man 2 to Baldur’s Gate 3, these follow-ups all looked at their predecessor, identified the weaker aspects, and directly addressed those issues.

The best weapons in Call of Duty: Modern Warfare 3

To the layman, every gun in Call of Duty: Modern Warfare 3 probably seems the same. They all shoot bullets, right? In reality, that couldn't be further from the truth. Even when you take player skill out of the equation, each gun has vastly different stats and applications that make some, even within their own category, just plain better choices for everyone. Each gun is broken down into various stats, including recoil, ADS speed, damage, and much more, which makes it hard to easily compare them. When you factor in just how many guns are available as you level up and keep unlocking more, the prospect of picking the best ones becomes overwhelming. If you're trying to build the ideal loadout to dominate the current meta, these are the best weapons in Call of Duty: Modern Warfare 3 for each weapon type.

We will detail the top picks per each class, and then list the rest in terms of how they rank.

Best Perk-a-Colas in Modern Warfare 3 zombies, ranked

A lineup of perk sodas from Call of Duty: Modern Warfare 3.

Ever since perks were introduced to the series, they've been a staple in every game mode in Call of Duty. For Call of Duty: Modern Warfare 3, you can obviously pick your perks during multiplayer, but not so in Zombies. This mode has always made perks work slightly differently, using different names, but similar mechanics. This time around, the Perk-a-Colas have returned, and these cans of refreshing soda just so happen to give your character a massive improvement. You can grab one from a vending machine on the map in exchange for your points, but they don't come cheap. Since these perks last you the rest of the match (or until used for some of them), you will want to choose your flavor wisely. These are all nine Perk-a-Colas in Call of Duty: Modern Warfare 3 ranked from best to worst.

It is important to note that the location where each perk machine spawns on the new Zombies map is random for every match. There's no way to know where any specific perk will be, but you can see where perk machines spawn on your map as indicated by a downward pointing arrow.
