Co-Op Games that Start as Simple Adventures, But Become Incredibly Dark by the End

Co-op video games tend to be more welcoming to families than games played alone. Many are designed as fun, simple party games that anyone can pick up and enjoy, regardless of age.

While many cooperative games are simple and lighthearted, a lot of them offer deeper gameplay and more sophisticated stories for players who want a more challenging and immersive experience.

Many cooperative games begin with straightforward stories, but as you get closer to the end, they frequently introduce surprising plot twists and discoveries that dramatically alter the game’s atmosphere.

Okay, so I’ve been thinking about games that really throw you for a loop. There are tons of co-op titles that start pretty normal – you’re just trying to survive, complete quests, whatever. But then, by the end, things get seriously messed up and dark. I’ve put together a list of 10 of those games where the story takes a major turn for the worse. It’s a wild ride, honestly!

Spoilers ahead for every game below.

10. LEGO Star Wars: The Video Game

Leaving the Galaxy in Darkness

TT Games’ LEGO games usually offer lighthearted takes on popular movies. While they often avoid or make fun of serious moments with LEGO humor, some games, like the original LEGO Star Wars: The Video Game, actually adapted darker scenes faithfully from the films.

TT Games’ very first LEGO title, LEGO Star Wars: The Video Game, was a fun, action-adventure game for two players to enjoy together. It playfully retold the story of the Star Wars prequel trilogy using LEGO bricks, and it came out just a few weeks before Star Wars: Episode III – Revenge of the Sith hit theaters.

Okay, so the game starts out just like the beginning of The Phantom Menace – you’re playing as Qui-Gon and Obi-Wan dealing with the Trade Federation blocking Naboo. But honestly, by the time you get to the stuff from Episode III, things get surprisingly intense, even though it’s a LEGO game! It gets pretty dark, which was a bit of a shock.

Despite attempts to change fate, Anakin Skywalker still falls to the dark side and Order 66 is enacted. However, the climactic battle on Mustafar is a player-versus-player fight where the Obi-Wan player must defeat Anakin as a final boss. This results in Skywalker suffering severe injuries, losing all his limbs, and ultimately transforming into the intimidating cyborg, Darth Vader.

9. A Way Out

Breakable Bonds

I’ve been following Hazelight Studios since they started up in 2014, and they’ve really become known for making awesome couch co-op games – keeping that whole style alive when a lot of developers were moving away from it. They usually make pretty fun, lighthearted games, but their first title, A Way Out, was seriously intense and dramatic – definitely their most serious game so far.

Unlike Hazelight’s previous games with fantastical elements, A Way Out feels very realistic. Set in the early 1970s, it tells the story of two prisoners, Vincent Moretti and Leo Caruso, who team up to get revenge on a criminal named Harvey who has harmed them both.

Although the game was advertised as being focused on a prison escape with cooperative gameplay, the prison section only lasts for around two hours. The rest of the game centers on the two main characters running from the police, reuniting with their spouses, and getting revenge on a man named Harvey.

Despite their close bond, it’s ultimately revealed that Vincent had been working undercover for the FBI. This leads to a deadly confrontation between them, with two possible outcomes: either Vincent lives and returns to his daughter, or Leo survives and goes on the run with his wife and son.

8. Tom Clancy’s Splinter Cell: Conviction

Following Orders

Many games focus on single-player campaigns, offering co-op as a side feature. However, sometimes these secondary co-op modes are more memorable than the main story, as was the case with Tom Clancy’s Splinter Cell: Conviction.

The main story in Conviction centers around Sam Fisher investigating his daughter’s death and a plot against the President. However, the game’s cooperative campaign takes place before these events, following the stories of agents Archer and Kestrel.

In this game, players take on the roles of Archer and Kestrel, working together to stop Russian criminals and military leaders from making illegal arms deals, all orchestrated by crime boss Andriy Kobin.

So, I was playing, and things got intense. Me and Kestrel managed to grab these EMP weapons and we were escaping on a plane, but then I got a direct order to take Kestrel out! We’d actually become pretty good friends during the mission, which made it even worse. The game forced me to sneak around and eliminate Kestrel, but just when I thought it was over, Kobin showed up and finished off whoever was still alive – leaving absolutely no witnesses. It was a total gut punch!

7. Brothers: A Tale of Two Sons

Brothers to the End

Unlike the other cooperative games mentioned, Brothers: A Tale of Two Sons is a more relaxed and peaceful experience with less emphasis on action. However, it still delivers a powerfully sad story by the end.

Brothers: A Tale of Two Sons is an adventure game played from an overhead perspective. It tells the story of two brothers, Naiee and Naia, who travel on a quest to find a cure for their ailing father, seeking healing water from the distant Tree of Life.

Players will experience a touching fantasy adventure where they control both brothers, working together to explore crumbling medieval castles, figure out tricky puzzles, avoid dangerous wildlife, and assist the people and magical creatures – like gryphons and trolls – they meet along the way.

Though the brothers succeed in finding water to save their father, the game concludes sadly. Naia, Naiee’s brother, is fatally wounded by a spider-like creature right after Naiee retrieves the water from the Tree.

6. Gears of War 2

The Scars of War

Okay, so Gears of War is famous for its over-the-top action and tough soldier characters, right? But honestly, underneath all the explosions and shooting, it’s a surprisingly dark series. It really gets into the emotional toll war takes on people – it’s not just about physical wounds, but the stuff that messes with your head and stays with you long after the battle is over. It’s way more emotionally impactful than you might expect.

The story of the Gears series truly comes to life in Gears of War 2. Players follow Marcus Fenix, Dominic Santiago, and Delta Squad as they launch Operation: Hollow Storm, a desperate mission to defeat the Locust horde in their underground tunnels on the planet Sera.

As Santiago travels, he discovers more and more evidence that his wife, Maria, isn’t actually gone—she’s been captured by the Locust in their city, Nexus. This discovery fuels his determination to rescue her, no matter what it takes.

Santiago and Fenix eventually located Maria, but found her tragically broken after weeks of abuse at the hands of the Locust. She had been starved, forced to work, tortured, and left in a permanent vegetative state following a lobotomy. Heartbroken, Santiago was forced to euthanize her, an act that deeply scarred him and haunted him for the remainder of the war.

5. Portal 2

Horrifying Fates

Though it doesn’t rely on typical shooting, Valve’s Portal 2 is famous for its incredibly well-designed first-person gameplay and captivating story set within the ruins of Aperture Science. However, many consider its cooperative multiplayer mode to be its most enduring achievement.

Following the story of Portal 2, the cooperative mode puts you in control of two robots, Atlas and P-Body. They begin by testing chambers designed to see how well two robots working together can handle tricky and hazardous challenges using portal guns.

Having proven their skill with portal technology, the robots were then assigned the job of retrieving old data storage and waking up thousands of frozen humans stored deep within the Aperture Science facility. This was done so the AI, GLaDOS, could restart her testing – and eliminate more humans.

In the cooperative Peer Review downloadable content, Atlas and P-Body are reactivated after GLaDOS eliminates the human test subjects. They’re assigned to deal with a bird that’s disrupting the facility. They succeed in scaring the bird away, but GLaDOS then takes its baby chicks and intends to raise them as weapons.

4. Far Cry 5

Prophetic Visions

Beginning with Far Cry 3, the Far Cry games have consistently offered co-op features, letting players team up to tackle the series’ often intense and unpredictable challenges. Far Cry 5 had the most notably grim and suspenseful co-op campaign of them all.

Far Cry 5 is an open-world first-person shooter set in the fictional Hope County, Montana. The game follows an unnamed deputy and local law enforcement as they attempt to arrest Joseph Seed, the leader of a dangerous cult. Seed has seized control of the county, believing he’s been chosen by God to protect humanity from an impending disaster.

You can’t start playing co-op in Far Cry 5 immediately. Both players first need to activate the radio tower on Dutch’s Island to unlock the co-op feature. In co-op, the second player controls a clone of the first player’s character.

Players can experience the story together, but a surprising and devastating ending is possible if they choose to arrest the villain, Seed. This decision will trigger a series of nuclear explosions, proving Seed’s prophecies were correct and ultimately creating the post-apocalyptic world featured in Far Cry New Dawn.

3. Call of Duty: Black Ops

An Explosive Zombie Ending

While most Call of Duty games don’t offer co-op campaigns, Call of Duty: Black Ops stands out by delivering one of the best first-person shooter co-op experiences ever created – Black Ops Zombies.

Building on the popular four-player Nazi Zombies mode from Call of Duty: World at War, Black Ops Zombies continues the story of Doctor Edward Richtofen, Tank Dempsey, Nikolai Belinski, and Takeo Masaki. They’re thrown through time and space, trying to end the zombie outbreak, and their journey begins in the Kino der Toten theater.

The group is then teleported across the globe, receiving help from other survivor groups based at the Pentagon and an abandoned film set in Siberia. Eventually, they arrive at Area 51, which serves as the launchpad for a final teleportation – this time to a secret lunar facility, revealed to be the origin of the zombie outbreak.

Okay, so basically, after a ton of crazy stuff, Richtofen finally manages to control all the zombies and tries to take over the world! It’s awful, but the few people left end up having to launch nukes to stop him. The problem is, it totally backfires – the Earth becomes a ruined, fiery wasteland… and it’s still full of zombies! It’s a really messed up ending, honestly.

2. Halo: Combat Evolved

Dust and Echoes

Among the most famous games to dramatically shift in mood mid-playthrough is Halo: Combat Evolved, which also happens to be a standout cooperative first-person shooter.

In the year 2552, as the spaceship Pillar of Autumnflees from the relentless alien Covenant, Combat Evolved tells the story of Master Chief, a powerful super-soldier. Along with the AI Cortana and other surviving humans, he fights to stop the Covenant and uncover the secrets of a strange, ring-shaped world called Halo.

Halo CE lets two players experience the campaign together in local co-op. However, the story officially portrays Master Chief as exploring the Halo ring alone, while his injured teammate, Linda-058, remains in a cryo-sleep pod in orbit.

Around the middle of the game Halo: Combat Evolved, the story takes a dramatic turn from typical sci-fi action to cosmic horror. Players discover that the Halo rings aren’t meant to save life, but to destroy it. They’re weapons of mass destruction intended to wipe out all life across a huge area of the galaxy, effectively starving the parasitic Flood – a zombie-like enemy that has already consumed countless civilizations in the distant past.

1. Dead Space 3

The Fall of Humanity

If you’re looking for a fantastic co-op game that begins as a straightforward adventure but takes a surprisingly dark turn towards the end, look no further than Visceral Game’s Dead Space 3, a third-person survival horror experience.

Set three years after the events of Dead Space 2, Dead Space 3 puts you back in control of Isaac Clarke, the troubled engineer. This time, he teams up with EarthGov soldier John Carver to search for Ellie Langford, another survivor from Dead Space 2. She disappeared while investigating the rumored origin planet of the Markers, the source of the terrifying Necromorphs.

The game Dead Space 3 begins with a straightforward rescue operation, but quickly expands when Clarke and Carver locate Langford. He persuades them to travel to the planet Tau Volantis, believing they can disable the Marker’s signal. Langford claims an ancient alien civilization once managed to contain a Necromorph outbreak, and their knowledge holds the key.

Okay, so it turns out those ancient aliens didn’t solve the Necromorph problem, they just put it off! They basically froze this huge moon – a ‘Brethren Moon’ – that was packed with Necromorphs. This moon was making those creepy Markers we’ve seen, all to help spread the Necromorphs and wipe out everything! Clarke and Carver did manage to destroy Volantis’ moon, which was awesome, but sadly, it wasn’t enough. Three other Brethren Moons are still out there, and they’re heading straight for Earth. It’s pretty terrifying, honestly.
