- Serious Sam The Third Encounter co-op supports online cooperative play plus shared/split-screen on the Steam listing.
- Role separation matters more than raw aim: assign long-range, close-range, and flank watchers.
- Movement lanes must stay open—most squad wipes start from clustering in one firing lane.
- Heavy ammunition coordination shortens boss fights and prevents waste.
- Exact player counts and final co-op features remain unconfirmed until release.
Co-op Modes and Confirmed Features
Serious Sam The Third Encounter is built by Croteam and published by Devolver Digital, and the official Steam listing confirms three core play formats. The game is still in early development with a TBA release date, so some multiplayer details remain unannounced.

The game is in early development. Co-op player counts, revive rules, and matchmaking details are unconfirmed—this guide focuses on confirmed features plus team strategies proven across the Serious Sam series.
Team Roles and Weapon Coordination
Cooperative Serious Sam combat rewards movement, communication, and role separation. Teams perform best when players avoid standing in the same firing lane, assign priority targets, and preserve heavy ammunition for encounters where concentrated damage matters.
Long-Range Specialist
- Handles Scorpions and Biomechanoids
- Sniper Rifle and Cannon focus
- Removes ranged pressure early
Close-Range Guard
- Stops Kleers, Gnaars, Werebulls
- Double Shotgun and Tommy Gun duty
- Protects flanks and teammates
Heavy Support
- Carries Devastator and rockets
- Focus fire on Khnum and bosses
- Controls emergency burst damage
| Weapon | Solo Value | Co-op Value | Best Use |
|---|---|---|---|
| Serious Bomb | Panic tool when surrounded | Team-saving wave clear | Dense hordes, boss windows |
| Cannon | Deletes priority targets | Assign one player to heavies | Armored, long-range threats |
| Devastator | Multi-threat control | Strong when lanes are clear | Clusters, arena waves |
| Rocket Launcher | Chokepoint control | Needs firing discipline | Groups, slow large targets |
| Double Shotgun | Immediate threat clearing | Protects against flankers | Kleers, Gnaars, Werebulls |
Call out heavy targets before firing the Cannon or Devastator. Focus fire shortens dangerous encounters and prevents two players from wasting heavy ammunition on the same enemy while a Khnum closes in.
Step-by-Step Co-op Session Setup
Follow these six steps to build a co-op session that survives the largest arena waves.
Choose the Correct Mode
Use solo play to learn weapon locations and enemy patterns, online co-op for coordinated sessions, and local split-screen when sharing one system and display.
Set Difficulty Before Starting
Start lower while the group learns enemy combinations, then raise difficulty. Avoid settings that force inexperienced players to burn heavy ammunition early.
Assign Battlefield Responsibilities
Divide encounters by threat type: one player on distant enemies, one on chargers, one watching flanks and supporting teammates.
Keep Movement Lanes Open
Do not stack directly behind another player, leave at least one retreat route open, and call out when crossing a teammate's firing lane.
Coordinate Heavy Ammunition
Reserve the Cannon, Devastator, and explosive weapons for priority targets. Fire explosives only when enemy formations are separated from teammates.
Recover After a Player Falls
Stabilize the arena first: eliminate charging enemies, use area damage to create a safe approach, and never rush into an active cluster without an escape route.
Enemy Threats in Co-op Play
Serious Sam encounters are built around enemy combinations rather than isolated duels. Identify the fastest melee threats, remove dangerous ranged units, and preserve movement space.
| Threat Category | Key Enemies | Threat Level | Squad Response |
|---|---|---|---|
| Rushing Melee | Kleer, Werebull, Gnaar | High | Bait charges, sidestep, close-range weapons |
| Ranged Suppression | Scorpion, Biomechanoid, Khnum | High to Very High | Long-range player removes them first |
| Heavy Assault | Scrapjack, Cucurbito, Lava Golem | Very High | Focus fire, keep distance, clear firing lanes |
| Boss-Scale | Ugh-Zan, Sirian Warship | Critical | Use full arena, save burst damage for openings |
Most failed co-op encounters begin when players cluster together or retreat through the same route. Spread across the arena while staying close enough to respond to a teammate's position.
Co-op Readiness Checklist
Before Your First Co-op Session:
- Confirm online co-op or split-screen setup with your team
- Agree on difficulty matching group experience
- Assign long-range, close-range, and support roles
- Review enemy priority order: chargers, then ranged, then heavies
- Agree on heavy ammunition callout rules
A team with average aim but clear callouts consistently outperforms a team of solo stars. Announce targets, lanes, and recoveries—short, direct calls work best.
