Looking for some co-op horror games for Halloween? You've come to the right place! Even though some would have you believe that there's no such thing as  multiplayer horror games, we very much beg to differ here at 2Game. In fact, as the games featured in this article will plainly show, co-op horror gaming is alive and well in 2021.

To be sure, all four major multiplayer titles we've got featured here fall squarely into the action-horror sub-category of the genre, as we had discussed before. This is okay, though! These are some of the best horror games anyway! I mean, when everything falls into place, dread comes easy. And in different ways, too.

For example, even though all four co-op horror games we've chosen for this article certainly are scary, they deliver their frights in very different ways. Sometimes, horror comes when you realize that you need to sneak through a whole platoon's worth of sleeping monstrosities. Other times, it's the thousands of ravenous undead rushing towards you. The diversity of scares is the beauty of the horror genre!

No matter what specific kind of scare you might be hoping to get, we've tried our best to make it happen. So, let's see what horror co-op games we've got for you!

Greatest Co-Op Horror Games

GTFO

More so than any other game on this list, GTFO is in a class all of its own when it comes to a co-op horror game. Up to four players take control of up to four prisoners as they make their descent into monster-infested underground facilities in a co-op fashion. From that point on, a potentially demented AI issues them with a variety of orders and objectives to be completed in a semi-sandboxed manner. A straightforward approach, but one that GTFO tackles incredibly well.

For one, this multiplayer game is remarkably brutal. Violence comes in short, vicious bursts. Sometimes, you'll get the drop on hideous Sleepers, but other times you might get tickled by their spinal probes, instead, triggering spawns in a wide radius around your crew. You can't handle every situation and objective with high-caliber ordnance, either. There's just not enough ammo to kill everything in a mission, so you'll need to sneak by some threats.

It's just an incredibly atmospheric and hardcore horror game experience. GTFO doesn't pull any punches, and it can be heart-achingly distressing at times. Sleepers are no joke, we can tell you that much.

Back 4 Blood

We'll admit right away - we didn't think Back 4 Blood would be nearly as good as it ended up being. The beta - as rocky as it might've been - was just that: a beta. The final product has got heaps of content, extremely fun gameplay loops, and genuinely adds something new to its niche. In fact, we even went on record saying that we think it's better than either Left 4 Dead game already! That's some high praise, in case you're not familiar with Valve's L4D.

What makes Back 4 Blood particularly relevant is that it offers an extremely engaging new take on cooperative horror gaming. Instead of relying on level-to-level sandboxing, it adds several unique progression systems to the mix. Weapons and characters are, therefore, way more interesting than ever before, and the addition of Cards serves as more than a novelty, too.

Back 4 Blood delivers a highly replayable experience and for more reasons than one. Of all the horror games on this list, it's probably going to keep players entertained the longest through sheer breadth of content. Be warned, though: there's no solo progression in this game whatsoever.

WWZ: Aftermath

Even though it's technically in the same niche as Back 4 Blood, WWZ: Aftermath is in fact a categorically different game. It's not a live-service horror game, for one. Instead, Aftermath's core progression systems rely on tried-and-true features. Think RPG-style upgrades, perk trees, gradual-yet-perceptible weapon improvements, and such.

Its frights, too, don't necessarily come from the creatures themselves. Instead, it's the sheer scale that WWZ's hordes command that will take newbies aback. For all its improvements and innovations, Back 4 Blood doesn't actually change how its monsters work. In most ways that matter, B4B's monsters are pretty much exactly the same thing we had seen dozens of times before. In WWZ, on the other hand, players square off against thousands of bodies all at once.

Here, the "undead" pile onto one another to get to players. They'll throw themselves onto your barricades by the dozens, and they'll expend literally all your ammunition with absolutely no regard for an individual's safety. All that matters is that they get to you - eventually. WWZ: Aftermath is pretty unique in this respect. Its highlight clashes are a glorious thing indeed, and you'll find no other game handles zombies even remotely similar.

Aliens: Fireteam Elite

Finally, we've got the oft-overlooked latest entry in the Aliens universe: Fireteam Elite. Right off the bat, we can tell you that we really enjoyed our time with the game! Mechanically, it's almost exactly what you'd expect out of a third-person bug hunt. What we hadn't expected, however, is that it would move the franchise forward in an interesting way, and explain things that even Ridley Scott's movies hadn't yet gotten to explaining.

The gameplay itself is pretty great, albeit we will admit that it can become monotonous in some sections. Namely, up to three Colonial Marines get to move through several different environs in an attempt to deal with the growingly more prominent Xenomorph infestation. Along the way, they come into contact with Weyland-Yutani synthetics and various types of Engineers' proto-synthetic lifeforms. For the most part, players will need to go from one objective marker to another, dealing with small pockets of Xenos along the way, and in-between major clashes.

What really makes Fireteam Elite pop, though, is that it's delightfully difficult even on middling modes. Its impressive bestiary leaves no quarter, and awesome guns and a truly engaging character-building system make for a stellar choice for some cooperating gaming on Halloween.

Get a party going with the best of Co-Op Horror Gaming!

Naturally, there are many more cooperative horror games on the market than just the four of these. Still, if you're intent on sticking with the freshest stuff on the market, they'll definitely be the best options for Halloween co-op gaming.

If you'd like to snag a few single-player horror experiences, too, why not check out our list of top horror titles of 2021? Some repeats, to be sure, but you may well be surprised by how many amazing terror-laden PC games we got this year.

Otherwise, we've also been looking at the horror game genre from outside the box. Just last week, for example, we talked about scary games that aren't actually horror-genre in the first place. A really fascinating topic, we feel! Namely, the 'horror games that ought to be made' article, which we also recommend you check out.

There's plenty more horror/Halloween content on the way, too. If you're into frights, for example, but don't have a good PC - we'll hook you right up. Stay tuned!
