Best Steam Co-Op Games for Diablo Fans (2026)

My squad has a very specific problem. We love the Diablo style loot treadmill, but we also have adult schedules. We want a game we can treat like Diablo without needing a second job to keep up.

If your group is in the same spot, this guide is for you. These are the Steam co-op games that scratch that Diablo itch with real builds, satisfying loot, and campaigns that a tired group of adults can actually finish.

Short answer: The best Steam co-op games for Diablo fans are Last Epoch, Path of Exile (private league or SSF style), Grim Dawn, and Warhammer 40,000: Inquisitor. For shorter sessions, look at V Rising and No Rest for the Wicked style hybrids.

Below I'll walk through how each game actually works for a real group of friends. Not just "does it have co-op," but how lobby flow, builds, and time commitment feel when you're trying to squeeze games in after bedtime.

What Makes a Good "Diablo Like" Co-Op Game?

When I say "Diablo like," I don't just mean isometric and there is loot. I mean that feeling of watching the screen explode while you argue about who gets the shiny thing on the ground. Good ARPG co-op on Steam has a few things in common.

• Clear roles and builds. Your squad should feel different. One person is the tanky bruiser, another is a glass cannon, someone is playing weird support.
• Easy to sync progress. It should not be a nightmare if someone misses a night. Catch up should be realistic, not a homework assignment.
• Low friction lobbies. Getting into a session needs to be 2-3 clicks. If your group has to fight the UI every time, you will bounce off the game fast.
• Reasonable grind. I like loot as much as anyone, but if it takes 40 hours to get a build online, my friend with twins is out.

With that lens in mind, let's look at the actual games that pull this off and what kind of squad they fit best.

Last Epoch: Best "We Wanted Diablo IV To Be Better" Pick

Last Epoch is the one I recommend first to most Diablo fans. It hits that modern ARPG feel without leaning so hard into seasonal systems that your whole group burns out.

Co-op runs up to four players and it works well for a steady weekly group. The skill tree system is deep, but you can be useful quickly. If one friend min-maxes builds and the rest of you just want to go pew pew, it handles both.

The downside is that it still has some "live service" DNA. New cycles and balance patches can make old build guides feel stale. If your squad plays once a week, you may want to pick one cycle, pick some simple builds, and ignore most of the meta chatter.

Grim Dawn: The Best "Campaign We Actually Finished" ARPG

Grim Dawn is older but it is still one of the best co-op ARPGs on Steam for a specific type of group. If your friends like the idea of a full story campaign that you can chip away at over a couple months, this is it.

The dual class system is incredible in co-op. One of my friends always ends up playing some kind of poison pet summoner. I tend to fall into a melee bruiser build. We get to be powerful in very different ways, and both roles feel useful when the screen fills with enemies.

The main trade off is that the game UI feels like an older PC game. It is totally playable, but if your group is used to the polish of Diablo IV, expect a small adjustment period. The upside is that once you settle in, there is a ton of content without a seasonal treadmill.

Path of Exile: Great If One Friend Loves Being The Guide

I have a soft spot for Path of Exile, but I only recommend it to squads where at least one person loves spreadsheets. The build system is wild in a good way and horrifying in a "oh no, I broke my character" way.

The trick for co-op is to treat it like a private league. Pick a chill set of builds, agree you are not racing the ladder, and let the build nerd of the group handle most of the planning. The rest of you can follow a simple guide and focus on blasting maps together.

If you try to play PoE like a casual campaign from the default menu, it will eat your group alive. If you frame it as "our weird ARPG science project" and keep expectations honest, it can be one of the best long running co-op games you play.

V Rising: Diablo Meets Valheim For Shorter Sessions

V Rising looks like a survival game at first glance, but if you squint at it like an ARPG fan it becomes very interesting. Combat feels closer to a Diablo style brawler than a typical survival game, and the base building gives your group a shared project.

Co-op lives on shared servers, so the trap here is letting one friend play ten hours between sessions. The fix is simple. Set expectations up front that you will all progress characters together and treat solo time as "gathering night" instead of boss pushing.

Where V Rising shines for Diablo fans is the boss design. Each V Blood fight gives you a new power or system, and figuring those out together feels a lot like unlocking a new skill in an ARPG. It is easier to hop in for a quick one hour session than most survival games.

How To Choose The Right One For Your Squad

When my group is trying to pick a new ARPG style game, we start with three simple questions.

• How often are we actually going to play this together in a normal week?
• Is anyone excited to be the build nerd or do we want "follow the guide" level depth?
• Are we in the mood for a story campaign, an endless grind, or a hybrid?

If we want a clear campaign that we can finish, we go for Grim Dawn. If we want a modern live service ARPG with seasons, we give Last Epoch a shot. When everyone feels like tinkering, we let our spreadsheet friend talk us into Path of Exile again.

Whatever you pick, be honest with each other about time and energy. The right game for your squad is the one you can actually stick with for more than two weekends.
