How Do U Get Cryptokeys in Black Ops 3

As well as delivering epic narratives and creating iconic characters, plenty of CoD campaigns have also offered a nice challenge down the years. So we've picked out the top 5 hardest CoD campaigns ever, and ranked them.

Whilst it's Call of Duty's multiplayer that understandably gets all the plaudits, the franchise has produced some incredibly good single-player experiences too – with Vanguard being the latest one. After all, before online gaming really got going in the mid-late 2000s, campaigns were the main selling point of FPS games.

Many games have since overlooked this aspect in favor of keeping players hooked to live service models. However, barring Call of Duty: Black Ops IIII, every major CoD title has had a campaign, and we've sifted through them all to rank the top five hardest of all time.

Hardest CoD campaigns ever ranked

We can confirm that we've played and beaten all these campaigns on the Veteran difficulty setting – apart from BLOPS III which we did on its debuting Realistic difficulty.

As most players will know, Veteran can turn a simple corridor into a test of patience that can take a long time. This separates the weak from the strong and is a perfect way to differentiate campaigns.

Recent years have phased out repsawning enemies and grenade spam, and as a result, have been a lot easier. But a trip down memory lane will dig up some of the most frustrating levels and sections in the series.

5. Call of Duty: Modern Warfare 2

Definitely not as tough as the later entries on our list, but Infinity Ward's second installment of the Modern Warfare saga had the odd mean level that will bring out the veins in your head.

The game actually starts out fairly generously for the first few levels, and then dumps a harsh one-two punch of Takedown on you, a nerve-inducing push through the Favela, and the extremely open nature of Wolverines.

You're allowed your breath back for a bit, and then you're plunged into the infested depths of the Gulag that has some positively vile checkpoints to clear. Through Whiskey Hotel and Loose Ends you have a ton of enemies to contend with and these are the levels that test your Veteran instincts, especially the survive and escape formula of Loose Ends.

Modern Warfare 2 doesn't have a defining level or section that stands out, it's just packed with lots of solid fights that will test your mettle.

4. Call of Duty 2

The early Call of Duty games set the standard for some of the difficulty that was going to be featured down the line.

CoD2 feels a bit more streamlined and thought-out compared to the first game, but it's still rife with grenades flying in from every angle and Germans that have had their skills honed by the Matrix.

There's definitely a sense that the levels get harder towards the end, as a natural difficulty curve should do. The German respawn factory never ceases production, even until the very end. The only thing that lessens the difficulty a tad is the fact that Call of Duty 2 introduced regenerating health for the first time, meaning players had time to recover.

3. Call of Duty 4: Modern Warfare

We consider CoD4 to be the best Call of Duty game, and its characters, set-pieces, that nuclear explosion scene, and so much more make this campaign memorable, not least the punishing difficulty.

But it's a handful of missions and sections that will get you used to the death screen. Charlie Don't Surf's push through the Broadcast area is painful, the Hunted is littered with large space and tight areas packed with enemies, and even scaling the hill in Safehouse can take a while.

But it's some of the game's final missions where things are turned up to 100. The iconic One Shot, One Kill mission is a supreme test of skill, patience, and luck on Veteran, No Fighting in the War Room is a timed slog through steam, claustrophobic corridors teeming with foes, and of course – Mile High Club.

A one-minute sprint through about 50 enemies in the tightest fighting area yet, going up a floor, demanding absolute precision and excellence on your part. You'll find that if you check many gamer's Trophies and Achievements for CoD4, they'll be missing this one on Veteran.

2. Call of Duty: World at War

Call of Duty: Grenade would've been a more apt title for Treyarch's 2008 World War II shooter and many players to this day still see grenade indicators appearing in their vision.

Every mission is an exercise in patience and bravery thanks to unlimited enemy respawns and the germans owning every grenade in existence.

The game is a brutal journey for its first 14 missions on Veteran, and then you get to what is probably the most difficult FPS mission ever created – Heart of the Reich. The act of taking down four AA guns can take literally hours as you have little cover, enemies are attacking (infinitely) from all sides, and you're having to constantly retreat from grenades every two seconds.

World at War is one of the last true tests of outrageous CoD difficulty.

1. Call of Duty 1 (Call of Duty: Classic)

Anyone who thinks World at War or CoD4 are the hardest campaigns only say that because they haven't the arduous task of completing the first-ever Call of Duty campaign on Veteran.

Why's it the hardest? It's very simple. No health regeneration, no health packs, the checkpoints are utterly unforgiving as you need to have a certain amount of health to trigger them, otherwise, you get diddly squat, checkpoints can be awarded as you're getting shot, enemies can regularly appear behind you, and they have an immaculate aim.

Then when you start to factor in Chateau, POW Camp, Eder Dam, Truck Ride, Battleship Tirpitz, and the absolutely mind-bogglingly difficult Pavlov's House, then it's easy to see why Call of Duty 1 has the hardest campaign ever.

Don't believe us? Go and play it on Veteran, then get back to us.


So that's our top 5 list of the hardest Call of Duty campaigns of all time. Even if your list has one or two slightly different entries, we can all agree that Call of Duty has done a great job of serving up some fiendishly tough treats.
