Steam Summer Sale: 20+ Great Online Co-op Games for Less than $10

In a tight spot with your group and trying to find a game to play on the cheap? Maybe one of these will do the trick.

Steam sales only come around a few times a year and PC gamers everywhere revere them as periods of amazing deals on games and terrible tragedies to their bank accounts.

If your group of friends is anything like mine, getting them all to both agree to and pay for a particular game is harder than herding feral cats. Maybe you're in a similar situation or maybe you're just on the prowl for some cheap multiplayer games. Whatever the case, we've compiled a sizable list to help you out.

All of the games listed below are:

  • Toting online co-op multiplayer for at least two players (most listed feature 4 player or more multiplayer)
  • Less than $10 so they're easy on your wallet

That sounds like a big win to me. Let's choo choo on through, and hopefully find you and your friend(s) a game you can play without stressing too much about cost.

Terraria

Sale price: $4.99
Steam Store link

You'll see this game mentioned on just about every list of co-op games. This co-op sandbox-adventure has loads of content for any group of friends to go to town on. Terraria has stayed on the top played Steam games for 7 years for good reason.

Grim Dawn

Sale price: $7.49
Steam Store link

If you're looking to scratch your ARPG itch, you could do a lot worse than Grim Dawn. Even without the expansion, you can find dozens of hours of whackin' and lootin' in Grim Dawn. If you're not too keen on its darker aesthetic but do want an ARPG, the next option may be more down your alley.

Torchlight 2

Sale price: $4.99
Steam Store link

It may be older than Grim Dawn, but Torchlight 2 still has a lot of staying power if you've never given the game a chance. There is more content to be found in Grim Dawn but Torchlight 2 has a robust array of mods available, including content, quality of life, and classes. This is still a solid buy today in 2018, and it can be modded for up to 8-player multiplayer.

Castle Crashers

Sale price: $4.49
Steam Store link

Another staple co-op game sure to be on pretty much every co-op list, Castle Crashers is the poster boy for co-op beat'em ups. This is an easy one for all ages and kill levels to get into and have fun with.

BattleBlock Theater

Sale price: $4.49
Steam Store link

Another game from The Behemoth, the same studio behind Castle Crashers. BattleBlock Theater's campaign is completely co-op and it also features a healthy selection of hectic PvP modes, for when you want to prove your better than your friends once and for all.

Rocket League

Sale price: $9.99
Steam Store link

Before you say, "Ugh, no. Too mainstream," take a breath and consider Rocket League as a co-op game with a low barrier of entry and a whole lot of speed. Rocket League may not be your first choice, but it's an easy game to get a group of people to agree to hop onto for a quick round.

Risk of Rain

Sale price: $2.49
Steam Store link

Risk of Rain is a co-op game with an unquenchable bloodlust. Though not for everyone due to its extreme difficulty, Risk of Rain is an easy buy for roguelite fans or groups of friends who hate life. It's a hard game and it will knock you down a peg with ease, whether you've got 1 hour or 300 hours worth of gameplay logged.

Beat Hazard

Sale price: $2.99
Steam Store link

This one always seems to slip through the cracks since it's been blessing Steam with its presence for eight years now, but despite its age, Beat Hazard continues to be a recommended purchase for co-op play, providing you and your friend(s) are good at shmups. Beat Hazard lets you use your own music or one of many radio stations to generate enemies, which is what makes this one so unique.

Ultimate Chicken Horse

Sale price: $7.49
Steam Store link

Playing this game with a group of friends is an exercise in sadism. You and up to three other friends will be tasked with creating and completing the stages in Ultimate Chicken Horse, and you can bet at least one (or even all) of you will make them nearly impossible to beat, in the name of being the better platformer player. Ridiculously fun and honestly not as enraging as it sounds.

Keep Talking and Nobody Explodes

Sale price: $5.99
Steam Store link

An outlier among the other games in this collection, Keep Talking and Nobody Explodes only requires one person to buy the game. There's a reason for that: Only one player is allowed to see the screen at a time, so only one can directly defuse the bomb. The other players must tell the defuser what to do based on the instructions in the manual.

If it sounds a little convoluted, that's because it is by design. Can you and your friends defuse a bomb? Maybe, maybe not. But you can certainly yell at each other trying.

Don't Starve Together

Sale price: $7.49
Steam Store link

Don't Starve has stood as one of the more accessible survival games over the years, and the multiplayer expansion Don't Starve Together may be an even more enjoyable game than the base with the Reign of Giants expansion. Together contains both, plus the ability to die in the forest with your friends. If -- as in my case -- you tried the original game but didn't enjoy it much, you may still find this fun.

Left 4 Dead 2

Sale price: $1.99
Steam Store link

You may be dissuaded from picking Left 4 Dead 2 up based on its age. It's been out for 11 years now, it seems like everyone's been through the game. Why bother? If you haven't played it yet, this is your reminder to pick up L4D2 to play with your friends. It's still fun to this day, but it's best played with friends. Any community for a decade-old game is bound to be elitist and this game is no exception.

PAYDAY 2

Sale price: $4.99
Steam Store link

If you don't play PAYDAY 2, it's possible the only thing you've heard about it was the hubbub about microtransactions a few years back. It's been a long time since then though, and the game is a solid heister. You don't need to play the first game to dive right into this one and, provided your group can cooperate, there are hours upon hours of heists for you to tackle.

Dungeon of The Endless

Sale price: $2.99
Steam Store link

How about something a little different? Amplitude's Endless universe has expanded this way and that, with "that" being Dungeon of the Endless, a pseudo-tower defense roguelike. In this, players must hoard resources and expand based on the ever-increasing threats of the depth of the dungeon. A single round in this game can take several hours and it is very hard, but if your group's into roguelikes you could do a lot worse.

Borderlands 2

Sale price: $4.99
Steam Store link

Borderlands 2 is another old staple that still holds up today, especially multiplayer. Pushing through this game with friends is satisfying as firefights are intense and the weapon system is a ARPG-style lootfest. Not many games age as well as this one -- you can come back years later and still have a ton of fun.

Golf With Your Friends

Sale price: $3.89
Steam Store link

If you just want a game to pay a little attention to while chatting, this is an easy choice. Golf With Your Friends isn't exactly rolling in content variety and only contains 7 levels with 18 holes, but things are kept fresh through golf ball shapes and game modes. A very easy game to just sit back and play while having a couple beers and a laugh.

Human: Fall Flat

Sale price: $7.49
Steam Store link

How about something a little less-in-your-face about its silliness? We've got some pretty quirky games listed here, but they're all a bit more obvious about it than the cooperative physics-based puzzle solving found in Human: Fall Flat. The one downside here is that there are not a lot of stages, but it's a good deal at this price. 

Project Zomboid

Sale price: $8.99
Steam Store link

Don't let this game's graphics and the year it entered Steam Early Access fool you: Project Zomboid is a fleshed-out survival sandbox with hundreds of potential hours of gameplay, with continued support from its developer as it slowly shambles toward full release. If you and your group can accept the high learning curve, you can have a great time with this game.

Portal 2

Sale price: $1.99
Steam Store link

The Portal games are famous for a lot of reasons and one of those reasons is (Spoilers!) the stellar co-op campaign. If you haven't played Portal 2 and you want a game to play with a friend, you may as well throw the $2 at Valve and see what all the hubbub is about.

Barony

Sale price: $2.24
Steam Store link

An other roguelike to add to the pile, Barony is the closest to a traditional roguelike of any of the games listed here. It looks old, it feels old, and it plays like an old game. That's perfectly fine: You'll be hard-pressed to find another game that takes the classic roguelike formula, turns it 3D and realtime, and allows for online co-op. This one's pretty niche but you're in for a good time if you're comfortable with classic roguelikes.

Endless Legend

Sale price: $7.49
Steam Store link

Though Endless Space is currently also on sale, I would recommend Endless Legend over it for its similarities to the Civilization series and its overall fun factor. This is a more traditional-style 4X game. Expand, form alliances, wage wars -- it's up to you. A worthy strategy addition to most gaming groups on a budget.

Resident Evil 5

Sale price: $4.99
Steam Store link

You don't hear much about Resident Evil 5 or 6 for a few reasons, but none of those reasons equate to them not being fun with friends. Resident Evil 5 is often overlooked in favor of 6 for co-op play because it retains the semi-tank controls found in its predecessor, but if you and a friend can adjust to that control style this is an intense and worthwhile co-op action game.

Resident Evil 6

Sale price: $7.49
Steam Store link

Like its predecessor, Resident Evil 6 is best played with a friend. Unlike its predecessor, it's got more modern, fluid controls and a whole lot of QTEs. This one is over-the-top in about every regard, to the extent I can't help but find it silly each playthrough. If you like classic Resi games, go with 5. If you can't deal with the antiquated controls, go with 6. The decision is as simple as that.

7 Days to Die

Sale price: $8.99
Steam Store link

One of the first titles in the survival game wave that paved the way for games such as Rust and ARK: Survival Evolved, 7 Days to Die still stands as one of the most played games on Steam and is just as fun now as when it came out. As with the two mentioned, 7 Days to Die allows you a great deal of freedom in your efforts to survive. Break, use, and do whatever you want to ensure your survival in a world overrun by over 50 types of zombies.

Orcs Must Die! 2

Sale price: $3.74
Steam Store link

The original Orcs Must Die! set off a chain reaction of action-tower defense clones, some good and some bad, but none really hold up to the sequel. Orcs Must Die! 2 is an improvement over the first game in almost every way, and has the added bonus of online multiplayer. It's easy to get into, easy to wrap your head around, and easy to spend too many hours in.

Tabletop Simulator

Sale price: $9.99
Steam Store link

This is a bit of a strange one since Tabletop Simulator itself isn't a game, but a mini-platform for tabletop gaming. The amount of games available via Tabletop Simulator are nearly endless, making this a fantastic purchase for any static group of friends who have trouble deciding on what to play or want to play board games without having to pick up after themselves.

---

These are definitely not all of the co-op games you can get for under $10 on Steam during this sale, but these are some I can personally recommend. I hope you've found at least one game you find worthy of your Steam library.
