Six co-op strategy games worth playing

#1

Best for automation and a long-lived shared project

Factorio

Co-op group size not yet verified

Why we picked it

Factorio turns cooperation into a shared engineering problem rather than simply placing two players in the same match. Its persistent world, clear division of labour and endless room for optimisation make it the strongest choice for groups that want a project to build over many evenings.

How co-op works
Online co-op on one persistent shared world. Players can drop in and out of the same save, and LAN play is supported.
Best with
2–4 people who can agree on who owns which part of the factory
Session fit
Long sessions, ongoing save — a project you return to for weeks

Before you play: Our catalog has no confirmed party-size limit for Factorio, so treat any large-group number you see elsewhere as unverified. In practice coordination gets harder fast — agree on area ownership before building.

AutomationShared worldDrop-in

Also consider: Prefer city-building, trade and a slower economic rhythm? Consider Anno 1800 instead.

#2

Best for an epic co-op campaign

Total War: WARHAMMER III

Co-op group size not yet verified

Why we picked it

Few strategy games let a group share a campaign at this scale. Each player controls a full faction, while diplomacy, turn planning and large real-time battles create the kind of stories that can carry a regular group for weeks.

How co-op works
Online co-op campaign: each player runs their own faction on a shared campaign map and can fight battles together.
Best with
2 players for a manageable campaign; more only with a committed group
Session fit
Recurring long sessions — campaigns run across many evenings

Before you play: Co-op campaigns need everyone present to progress the shared turn cycle. Expect scheduling, not spontaneity.

Grand strategyCampaignTurn + battles

Also consider: Want turn-based empire-building without real-time battles? Consider Age of Wonders 4 instead.

#3

Best for modern rts co-op versus ai

Age of Empires IV: Anniversary Edition

Co-op group size not yet verified

Why we picked it

Age of Empires IV is the easiest recommendation for a group that wants traditional RTS teamwork without committing to a persistent campaign. Teaming up against AI gives everyone room to specialise while keeping each session self-contained.

How co-op works
Online same-team play in custom and skirmish matches, typically against AI opponents.
Best with
2–4 on a team so each player owns a front or a role
Session fit
Classic 1–2 hour sessions with a clear start and end

Before you play: This is team-versus-AI rather than a shared campaign save — progress does not carry over between matches.

Also consider: Need a shorter tactical session with less base management? Consider Mechabellum instead.

#4

Best for shared economy and city building

Anno 1800

Co-op group size not yet verified

Why we picked it

Anno 1800 makes cooperation feel economic rather than combative. Coordinating production chains, trade routes and expansion creates a slower, more conversational form of teamwork that suits groups who enjoy planning as much as winning.

How co-op works
Online multiplayer where players build and trade in the same session; co-op groups can share control of an economy.
Best with
2–3 builders who enjoy planning together rather than racing
Session fit
Long sessions on an ongoing save

Before you play: Sessions rely on the host's save, so plan when you can all play before committing to a world.

City buildingEconomyTrade

Also consider: Want deeper automation and fewer trade routes to manage? Consider Factorio instead.

#5

Best for turn-based 4x strategy

Age of Wonders 4

Co-op group size not yet verified

Why we picked it

Age of Wonders 4 is the best fit here for players who prefer deliberate turns, empire customisation and long-term planning. Team play lets allies build complementary factions without the pressure of real-time execution.

How co-op works
Online multiplayer with teams, so allied players can play a shared 4X campaign against AI rivals.
Best with
2 allies for fast turns; larger teams slow the round down
Session fit
Multi-session commitment — turn-based games rarely finish in one evening

Before you play: Turn times grow with player count. Agree on simultaneous turns and a session end time.

4XTurn-basedTeams

Also consider: Prefer real-time battles and a larger fantasy campaign? Consider Total War: WARHAMMER III instead.

#6

Best for shorter tactical co-op sessions

Mechabellum

Co-op group size not yet verified

Why we picked it

Mechabellum earns its place because it delivers meaningful tactical cooperation without asking for an entire evening. The dedicated two-player Survival mode rewards coordinated counters and positioning, while remaining easy to return to for one more run.

How co-op works
Online play with a dedicated 2-player co-op Survival mode, plus 2v2 team play against other players.
Best with
2 players — the co-op experience is built for a duo
Session fit
Short tactical sessions, roughly half an hour

Before you play: 2v2 is competitive PvP, not co-op. Pick Survival if you want to play with someone rather than against them.

Also consider: Want a full base-building RTS instead of short tactical rounds? Consider Age of Empires IV instead.

Tips for Your Group

  • Match the game to the time you actually have. Mechabellum suits a short evening; Factorio, Anno 1800 and campaign games need recurring sessions.
  • Agree on ownership before you build. In Factorio and Anno 1800, divide factories, islands or production chains so players can work in parallel.
  • For campaign games, set a fixed session cadence. Total War: WARHAMMER III and Age of Wonders 4 lose momentum when the group goes weeks between turns.
  • In RTS matches, assign roles early: economy, scouting, defence and pressure. Clear responsibilities make co-op against AI more satisfying.
  • Choose the host carefully for persistent saves. Confirm who can reliably be online before starting a long-running world.

How we chose these games

We selected games where cooperation meaningfully changes how the strategy works—not games that simply allow multiple people in the same lobby.

  • Co-op quality: Players need to coordinate plans, roles or resources rather than play parallel solo games.
  • Group fit: We consider the verified co-op player range, practical group size and whether the game works for a single evening or a recurring group.
  • Trade-offs: Every main recommendation includes the commitment or limitation a group should understand before buying.
  • Facts and judgement: Player counts and mode labels come from Co-Op Now's canonical game records. The ranking, group-fit advice and “Why we picked it” sections are editorial judgements.

Frequently Asked Questions

What is the best co-op RTS?

Age of Empires IV is our best modern RTS pick because a group can team up against AI, divide economic and military roles, and finish a match in one sitting. Age of Empires II: Definitive Edition is the stronger choice if your group prefers a classic RTS and co-op campaign content.

What is the best co-op strategy game for two players?

Choose Factorio for a long-running shared project, Mechabellum for short tactical sessions, or Age of Wonders 4 for a turn-based campaign. All three work well as a duo, but they demand very different amounts of time.

Which strategy games support campaign co-op?

Among the six main picks, Total War: WARHAMMER III and Age of Wonders 4 are the clearest campaign choices. Gloomhaven and Warhammer 40,000: Rogue Trader in the extended list also offer story-driven campaign co-op.

Which co-op strategy game has the most replay value?

Factorio offers the deepest long-term shared project, while Total War: WARHAMMER III, Anno 1800 and Age of Wonders 4 provide repeat campaigns built around different factions, maps or strategic choices.

Which co-op strategy games support LAN play?

Factorio supports LAN and is the clearest LAN recommendation among the six main picks. Age of Empires II: Definitive Edition in the extended list also supports LAN. Most of the other games on this page are primarily designed for online co-op.

What is the easiest co-op strategy game for beginners?

Age of Empires IV against AI is the most approachable traditional RTS in the main list. For a lower-pressure introduction to strategy, Bloons TD 6 and Unrailed! are easier to learn and work well in short sessions.

Do these games require a powerful PC?

Total War: WARHAMMER III and Anno 1800 are the most demanding main picks. Factorio and Mechabellum are generally easier to run. Use the PC requirements checker on each game page before your group buys multiple copies.
