How Online 404 Multiplayer Works
Online 404 is a first-person open-world survival game from Cornfield Games set in the quarantined Leminsgale District. The Steam listing confirms Single-player and Online Co-op as the supported modes, meaning the story can be completed alone or with a group of up to 4 players working through the same campaign.
Co-op is not a separate mode tacked onto the game. Groups share one survival world: one shelter, one growing stockpile, and one hostile district. That shared structure makes teamwork the most efficient way to handle the game's core systems.

A full 4-player team can split scouting, gathering, crafting, and base defense simultaneously. Smaller groups should reduce their exploration radius and reinforce the shelter earlier, since fewer hands means slower progress on every front.
Solo vs Co-op Comparison
Choosing between solo and multiplayer changes how you approach nearly every system in the game.
| Aspect | Solo Play | 4-Player Co-op |
|---|---|---|
| Story progression | Full story, slower pace | Shared story, faster objectives |
| Resource gathering | One load at a time | Parallel gathering routes |
| Base building | Linear upgrades only | Simultaneous construction tasks |
| Combat | No backup, retreat often | Flanking and covering fire |
| Shelter raids | Defend alone | Assigned defensive positions |
| Food demand | Low | High, plan farming early |
In co-op, a reckless teammate can drag the whole group into a fight far from shelter. Agree on engagement rules before entering unfamiliar areas, and always identify escape routes as a team.
Play Solo If You Want
- Full control of pacing and decisions
- Careful, methodical exploration
- Lower food and supply pressure
- A personal long-term survival project
Play Co-op If You Want
- Faster progression through objectives
- Divided roles and shared workload
- Stronger shelter raid defense
- Company during long expeditions
Team Roles and Character Choices
The game offers four playable characters, each with different starting gear and stats. In a 4-player group, complementary picks make early survival tasks much easier to divide.
| Role | Focus | Key Tasks |
|---|---|---|
| Scout | Navigation, smartphone use | Map routes, weather checks, research |
| Gatherer | Scavenging, farming | Materials, food stockpile, crafting supplies |
| Builder | Base construction | Shelter, wooden defenses, vehicle parts |
| Fighter | Combat readiness | Weapon upkeep, raid defense, hunting |
Compare each character's starting equipment and stats before committing. In co-op, a group that stacks similar characters will struggle in the area nobody covered, while complementary starting strengths smooth out the entire early game.
Co-op Survival Workflow: Step by Step
Follow this sequence when starting a fresh multiplayer run in Leminsgale District.
Gather Essential Materials
Send the group to scavenge the starting area for materials that support crafting, repairs, and shelter work. Split directions and meet back at a fixed point.
Master the Smartphone Tools
Assign one player as primary navigator. The smartphone provides the map, flashlight, weather forecast, and the in-game Internet for crafting research.
Establish a Shared Shelter
Pick a defensible location and build together. A shared base stores group resources and anchors every expedition.
Add Defenses and Utilities
Reinforce walls with wood, salvage vehicle parts like doors and hoods for stronger structures, and work toward electricity as a longer-term goal.
Expand Exploration Gradually
Use short, planned trips before attempting distant objectives. Restoring a working vehicle is a major milestone that unlocks long-distance exploration.
The strongest co-op loop is two players scavenging while one builds and one researches crafting instructions on the in-game Internet. Rotate roles so nobody burns out on one task.
Multiplayer Raids, Hunting and Expeditions
Hostile inhabitants make the district dangerous, and shelters can come under attack. Co-op preparation determines whether a raid is a setback or a routine defense.
| Activity | Solo Difficulty | Co-op Advantage | Preparation |
|---|---|---|---|
| Shelter raids | High | Assigned positions, overlapping cover | Reinforced walls, stored supplies |
| Hunting | Moderate | Drivers, spotters, carriers | Weapons, food reserves |
| Exploration combat | High | Flanking, mutual retreat | Escape routes, recovery items |
| Vehicle restoration | Slow | Parallel parts scavenging | Saved components, tools |
Reinforce the shelter before hostile pressure arrives, not during an attack. Control enemy approach routes using the base structure and protect the group's critical supply stockpile first.
Co-op Session Checklist:
- Confirm character roles and starting gear
- Set a shared shelter location
- Stockpile reserve food and recovery supplies
- Reinforce walls and plan raid positions
- Check weather forecast before long trips
