This far far west co-op guide covers what most multiplayer write-ups skip: spell reactions fire cross-player, and that changes how you build your crew. The bounty-hunting loop works solo, but the game's reaction system only reaches full output with deliberate pairing.
Spell reactions in Far Far West fire whenever the setup condition and trigger condition land on the same target, regardless of who cast them. Two players with different schools hitting the same enemy produce reactions that neither could generate alone. That mechanic is the reason a coordinated crew clears faster than four people running the same spell loadout.
TL;DR: Far Far West supports 1-4 player online co-op. Spell reactions fire cross-player — pair different schools deliberately for maximum reaction output. After every boss, an infinite wave spawns immediately; split roles (extractor, rear guard, looters) before the boss dies so your crew isn't scrambling. Steam Remote Play Together lets friends without a copy join your session. Recommended compositions and role breakdowns below.
Key Takeaways
- Up to 4 players online co-op; Far Far West is designed around crew play
- Spell reactions trigger cross-player — Acid + Electric from two players generates Chain Spark
- Boss death spawns infinite waves immediately — clear the map before engaging the boss
- Designate roles before boss fights: extractor, rear guard, and damage dealers
- Steam Remote Play Together allows a friend without the game to join; host needs 15 Mbps upload
- Strongest 2-player pairing: Voodoo + Electric for Hex Mark into Chain Spark reactions
- 4-player ideal: Pyro burst, Electric chains, Voodoo debuffs, Cactus turrets for passive add management
How Co-op Works in Far Far West
Far Far West's co-op is crew-based. From the main menu, create a crew session or join an existing one. Crew types:
- Open — any player can join
- Friends only — Steam friends list only
- Invite — send a lobby code directly
Your crew persists across contracts. The same four players carry over from mission to mission without re-queuing. The session host owns the mission selection; everyone else votes on difficulty and contract type.
The game scales enemy count and density with crew size, so a 4-player session has more enemies than solo, but spell reactions, revives, and role distribution more than offset the difficulty increase. A full crew consistently clears harder contracts faster than a solo player could on the equivalent difficulty.
Steam Remote Play Together. If a friend doesn't own Far Far West, they can still join via Steam Remote Play Together:
- Launch Far Far West and open Steam Overlay (
Shift + Tab) - Right-click your friend in the Friends List
- Select "Remote Play Together"
- Assign input: host keeps keyboard/mouse, guest uses controller
- Your friend joins your session via stream; only you need a copy of the game
Remote Play needs at least 15 Mbps upload from the host. Below that threshold, input lag becomes noticeable during fast boss encounters.
How Spell Reactions Fire Cross-Player
This is the mechanic most co-op guides skip entirely. Far Far West's spell reaction system doesn't check who applied the setup — it checks whether the setup and trigger conditions are present on the target.
Say Player A hits an enemy with Acid's Corrosive Spit, applying the Corrosive status. Player B hits the same enemy with Electric's Chain Spark. The Corrosive + Electric reaction fires (acid-amplified chain), dealing significantly more damage than either spell delivers alone.
This means deliberate spell pairing between teammates generates reaction chains that a single player running both schools can't produce as efficiently. You only have four spell slots, but two players have eight.
Cross-player pairings worth building around:
| Player A School | Player B School | Reaction Output |
|---|---|---|
| Voodoo | Any damage school | Hex Mark multiplies all damage |
| Acid | Electric | Chain Spark + corrosion amplification |
| Pyro | Cactus | Fire ignites thorn explosions for area burst |
| Electric | Acid | Staggered chain with corrosion DoT |
In practice: designate one player as setup and one as trigger. In a 4-player crew, one Voodoo player opening with Hex Mark on every target boosts the whole team's damage without any further coordination. Hex Mark stacks regardless of damage source. The other three players just play normally.

Roles in Co-op
A Far Far West crew of four covers more ground with intentional role assignment than with four identical builds. Suggested roles:
One player runs Pyro as the burst dealer. Inferno Burst and Fire Tornado deal the highest single-target damage during boss vulnerability windows. Save major cooldowns for those windows and unload completely when they open.
The Electric chain caster handles add waves, secondary targets, and post-boss infinite wave suppression. Chain Spark hits multiple targets during movement without precise aim. Electric's mobility options also make this the natural extractor role, since it's fastest to the extraction point when the boss dies.
A Voodoo player opens every encounter with Hex Mark, which stacks a damage debuff on any target hit. One Hex Mark player amplifies the full crew's damage output for the rest of the fight. It applies to every damage source. No coordination required beyond "cast it first."
The Cactus turret handler places thorn turrets at chokepoints before boss fights start. Turrets handle add waves passively while the rest of the crew focuses the boss. It's the most forgiving role mechanically and the most valuable in add-heavy encounters.
In a 2-player crew, Voodoo + Electric is the most consistent pairing. Hex Mark into Chain Spark produces the best cross-player reaction output while covering both adds and single-target damage.
Boss Encounters in Co-op
The biggest difference between solo and co-op boss fights isn't damage speed. It's post-boss wave management. When the boss dies, an infinite enemy wave starts immediately. In solo, you make a decision: extract now or risk more loot. In co-op, you can split the team.
Before the boss triggers:
- Clear the full map first, same as solo
- Designate one player as the extractor and one as the rear guard before engaging
- The extractor moves toward the extraction point the moment the boss dies
- The rear guard holds the spawn point, buying time for any remaining loot collection
- The burst dealer and turret handler handle the boss, then the burst dealer assists the rear guard after boss death
The Ghost Train's phase two bandit management is much easier with a dedicated Electric chain caster on adds. The burst dealer saves everything for the engine core window. In solo you're juggling bandits and the cannon simultaneously; in a 4-player crew the burst dealer shouldn't touch bandits at all.
The Undead Spellcaster is the easiest far far west co-op boss because its two demands split naturally between players. Turret handler places Cactus turrets, burst dealer focuses the Spellcaster, chain caster handles overflow adds.

Co-op Tips
Assign roles before queueing, not during. The most common co-op breakdown happens at the boss transition: nobody knows who's handling adds because the group assumed someone else would. One sentence before the session starts ("I'm doing Cactus turrets, you handle the cannon") prevents most of it.
Don't run duplicate schools. Four Pyro builds deal great boss damage and nothing else. Add waves, the infinite post-boss spawn, and crowd-control-dependent fights all become harder. Variety is mechanically stronger, not just stylistically.
Share Joker cards with the group. Joker cards affect individual builds, but some (particularly the ones that spawn healing or resource pickups) benefit the full crew. Coordinate Joker picks the same way you'd coordinate class selection in any looter.
Use the buddy revive. In co-op, downed players stay in the revive window for several seconds. The chain caster or turret handler should be the default revive role — they have the most mobility and the most hands free. The burst dealer should not be the primary reviver; their cooldowns are too valuable for boss windows.
Pre-clear before the last region. In high-difficulty contracts, the final region's infinite wave after the boss is the main run-ender. If you don't have strong add suppression, don't push the boss without at least one Cactus turret player or Electric chain caster primed.
Frequently Asked Questions
Q: Is Far Far West co-op or single player? A: Both. Far Far West is designed for 1-4 player co-op but solo play is fully supported with all mechanics intact. Co-op unlocks the spell reaction cross-player system in full, making it mechanically distinct from solo rather than just easier.
Q: Do you need to own Far Far West to play co-op with a friend? A: Not always. Steam Remote Play Together lets a friend join your session via stream — only the session host needs a copy. The guest needs a controller and at least a stable internet connection. Host needs 15 Mbps upload for smooth play.
Q: Does difficulty scale in Far Far West co-op? A: Yes, enemy count and density increase with more players. A 4-player session has more enemies than a solo session on the same contract. The increased difficulty is offset by revives, role splitting, and the more efficient spell reaction chains that a coordinated crew generates.
Q: Can you play Far Far West co-op with randoms? A: Yes. Set your crew session to Open to allow any player to join. Random matchmaking fills your crew from the public pool. The experience is less coordinated than playing with friends — role assignment and spell pairing require communication — but the base co-op loop works fine with randoms on standard difficulty.
Q: Are there co-op exclusive rewards in Far Far West? A: No co-op exclusive rewards in the current Early Access build. All Joker cards, weapons, and spells are available in both solo and co-op. The co-op advantage is efficiency — faster map clears, better add management on hard contracts, and more consistent boss kills — rather than exclusive drops.
