Gears of War: E-Day pulling Horde Siege back to the front of the marketing beat reminds everyone that the horde format still owns a specific evening on PC. A pot of coffee, three friends on voice, and waves of enemies pushing at fixed positions for an hour. It has been the answer to “what do we play tonight” since Left 4 Dead landed in 2008 and nothing has quite replaced it.
These seven horde mode co-op games for PC all keep the four-player-plus-waves DNA intact, live on Steam with active servers in 2026, and reward voice-first cooperation over lone-wolf hero work.
What to look for in a PC horde game
- Real four-player co-op. Two-player horde is possible; the format sings at four.
- Distinct roles. Classes, weapon specialisms, or map roles that give each player a job.
- A progression loop that rewards session-length play. Not just cosmetics.
- Anti-cheat that keeps random pubs playable.
- Server browser or matchmaking that finds players in your region and skill.
- Mod support for late-life longevity. Vermintide 2 and DRG both live on their mods.

The 7 best horde mode co-op games for PC in 2026
1. Deep Rock Galactic, best procedural cave co-op
Deep Rock Galactic is the reference PC horde game of the last five years. Four space dwarves, procedurally generated caves, class specialisms (Driller, Engineer, Gunner, Scout), and swarms of glyphids that scale with the party.
Ghost Ship’s live game cadence has been exemplary. Free seasons, new frameworks, and a small paid supporter pack for players who want to give back. The classes remain distinct enough that a good group divides labor without a leader dictating.
Where it falls short: The mission variance ceiling is capped by the procedural generator. After 200 hours the maps rhyme.
Pricing:
- Paid up front. Regular deep discounts on Steam.
- vs Vermintide 2: More systemic, less melee-focused.
Platforms: Windows, Linux via Proton.
Download: Available on Steam, Xbox Game Pass on PC, and the Microsoft Store.
Bottom line: Buy Deep Rock Galactic first if you have never played a modern PC horde game.
2. Killing Floor 2, best round-based Zed clearing
Killing Floor 2 by Tripwire remains the go-to physics-driven horde shooter. Six players versus a wave-based rush of Zeds, with a trader phase between rounds where you spend cash on weapons and perks.
The gore system is still the most satisfying on this list. Weapon feel is heavy. Objective and Endless modes give the wave structure some variety.
Where it falls short: Ownership hopped to a new steward in the past year and content updates slowed. The community server culture keeps it playable.
Pricing:
- Paid up front. Regular deep discounts on Steam.
- vs Left 4 Dead 2: Slower, more customization, more shopping.
Platforms: Windows, Linux, macOS legacy.
Download: Available on Steam, the Epic Games Store, and the Microsoft Store.
Bottom line: Buy Killing Floor 2 if you want round-based horde with a shop phase.
3. Warhammer: Vermintide 2, best melee-first swarm co-op
Warhammer: Vermintide 2 by Fatshark is the deepest melee-first horde game on PC. Four heroes with distinct career trees, Skaven and Chaos hordes, and a mission structure that feels closer to Left 4 Dead than to Deep Rock Galactic.
The combat weight is unlike anything else. Elf Kerillian’s dodge cadence, Bardin’s shield uptime, and Sienna’s staff builds create actual party synergies.
Where it falls short: Solo AI teammates are mediocre. Best experienced with human friends.
Pricing:
- Paid up front. Regular seasonal sales.
- vs Darktide: Better balanced classes, weaker firearms.
Platforms: Windows.
Download: Available on Steam, the Epic Games Store, and the Microsoft Store.
Bottom line: Buy Vermintide 2 if you want the deepest melee horde game on PC.
4. Warhammer 40,000: Darktide, best 40K swarm co-op
Warhammer 40,000: Darktide is Fatshark’s follow-up to Vermintide, set in the 40K universe. The bolter, the lasgun, and the various melee options give it a gunplay-plus-melee mix that Vermintide never attempted.
Content cadence caught up to expectations through 2025 and beyond. The Hab Dreyko update and the Traitor Curse arc landed well, and the mission board rotates enough variety to keep a group of four coming back.
Where it falls short: RNG on curios and blessings can gate top-tier builds. Class balance is a moving target between patches.
Pricing:
- Paid up front. Regular sales.
- vs Vermintide 2: Better firearms, less balanced classes.
Platforms: Windows.
Download: Available on Steam, the Microsoft Store, and Xbox Game Pass on PC.
Bottom line: Buy Darktide if you want ranged-plus-melee horde in the 40K universe.
5. Left 4 Dead 2, best reference co-op zombie run
Left 4 Dead 2 is the game that started this whole conversation and remains the reference point. Four survivors, a director AI that seeds hordes based on tension, and a small library of iconic campaigns that still land in a two-hour session.
The mod scene is enormous. Custom campaigns, custom infected, and workshop content keep the game feeling fresh 15+ years after release. Steam sales put it under $2 regularly.
Where it falls short: Old-school gunplay. Some pubs still run cheat-ridden servers.
Pricing:
- Paid up front. Regularly on deep discount on Steam.
- vs Vermintide 2: Cheaper, faster, less deep.
Platforms: Windows, macOS legacy, Linux native.
Download: Available on Steam.
Bottom line: Buy Left 4 Dead 2 as the cheap entry point to the whole horde format.
6. GTFO, best stealth-first horde raid
GTFO by 10 Chambers is the anti-Left-4-Dead. Four players creep through a research facility, take enemies out silently one at a time, and manage the noise budget until the objective phase forces a horde. Then the loudness explodes.
Its Rundown system releases a fresh season of missions with a full reset. Coordination is mandatory. Solo play is possible but painful.
Where it falls short: Unforgiving to new players. A single mistake wipes the run.
Pricing:
- Paid up front.
- vs Vermintide 2: More stealth, more coordination, less button-mashing.
Platforms: Windows.
Download: Available on Steam.
Bottom line: Buy GTFO if you want the tightest, most demanding horde game on PC.
7. Zombie Army 4: Dead War, best third-person WW2 undead
Zombie Army 4: Dead War by Rebellion is a third-person co-op shooter set in a Nazi zombie universe. Four players clear waves with sniper rifles, shotguns, and pistols, with the X-ray killcam that Rebellion carried over from Sniper Elite.
The tone is deliberately campy. The set-pieces (huge tanks, undead sharks, floating fortresses) are the reason to keep playing. Sales put it in a low price bracket often.
Where it falls short: Not as long-lived as Vermintide or DRG. The player base ebbs and flows.
Pricing:
- Paid up front. Frequently on sale.
- vs Left 4 Dead 2: Third-person, more scripted, more over-the-top.
Platforms: Windows.
Download: Available on Steam and the Epic Games Store.
Bottom line: Buy Zombie Army 4 if you want a third-person co-op shooter with X-ray killcam absurdity.
Bonus pick: Payday 3, heist-plus-waves for the crew
Payday 3 ships a heist phase followed by a cop siege phase where enemy waves push you off the vault. Not a pure horde game but the siege scratches the same itch.
Bottom line: Consider Payday 3 as a change of pace from purebred horde shooters.
How to pick the right one
- Buy Deep Rock Galactic first. It is the most balanced modern horde game.
- Buy Killing Floor 2 if you want a wave-and-shop rhythm.

- Buy Left 4 Dead 2 as the cheap entry point and mod-heavy classic.
- Buy GTFO if you have a coordinated squad and want the tightest challenge.
- Buy Zombie Army 4 for third-person over-the-top set pieces.
- Consider Payday 3 if you want the horde format inside a heist wrapper.
