Left 4 Dead 2 co-op with 8 survivors
Bring the whole group through the campaign, not just four.
Left 4 Dead 2 caps co-op at 4 survivors, but a dedicated server with the L4DToolZ extension and a SourceMod multislots plugin runs campaigns with 8. It is a server side change only, players install nothing, and 8 player co-op with plugins and a few custom campaigns sits well on our 3 GB plan for $7.99 a month.

Everything 8 player co-op needs
Can Left 4 Dead 2 have more than 4 players in co-op?
Not in the base game. Co-op stops at four survivors and Versus at eight players. On a dedicated server, L4DToolZ raises the client and player limits, and a multislots plugin gives every extra player a survivor to control. Without that plugin, players five to eight just spectate.
You need file access to do it, and that is what our server gives you: a file manager, SFTP and a live console.
How do you set it up?
Upload MetaMod:Source and SourceMod into the left4dead2 folder and restart. Then unzip the latest L4DToolZ release into left4dead2/addons, start the server and type plugin_print in the console to check it loaded. If it is missing, the files are usually one folder too deep.
In left4dead2/cfg/server.cfg, add sv_maxplayers 8, sv_force_unreserved 1, sv_allow_lobby_connect_only 0 and sv_visiblemaxplayers 8. Then, with nobody connected, run sv_setmax 31 in the console and change map. The L4DToolZ readme advises never going above 31, because higher values have crashed servers since The Last Stand update.
Finally, upload a maintained multislots plugin to addons/sourcemod/plugins, restart and check it with sm plugins list. Most write their settings to cfg/sourcemod on the first run, including the maximum survivors.
Why do players have to join with connect?
A lobby reserves the server and sets the limit back to the game's own: four for campaigns. sv_force_unreserved 1 makes the server ignore lobby reservations, so players join directly. Each player turns on the developer console in the keyboard and mouse options, presses ~ and types connect followed by the server address.
Balancing a campaign for eight
The AI Director still spawns hordes and items as if for four, so eight survivors walk through. Raise the difficulty one step first. Many multislots plugins spawn an extra kit with each extra survivor, and some finales only count four, which a finale fix plugin solves. Some custom campaigns assume four survivors, so test one before a big night.
Take a backup before adding a batch of plugins, so a broken one is a quick restore. After a game update, MetaMod:Source, SourceMod and L4DToolZ may need updating too. A long plugin list with many Workshop campaigns is where the 4 GB plan fits.

Common problems
Server not responding
Make sure the server is online. Servers sleep after 4 days with nobody playing, and anyone with access can start them again from the dashboard in one click.
Use the server address
Do not use localhost, 127.0.0.1 or your own IP from a home hosting guide. Copy the exact address of the server.
No port forwarding or firewall changes
Opening ports on your router is only for hosting a server at home, so there is nothing to change to join this one. If Windows asks whether to let the game through the firewall, choose Allow.
Common questions
How much does a Left 4 Dead 2 server cost?
Left 4 Dead 2 servers start at $1.25 for 3 days, with no subscription. Monthly plans are 2 GB at $4.99, 3 GB at $7.99 and 4 GB at $9.99. Pay monthly or prepaid, split the bill with friends, and cancel any time.
Do players need mods to join an 8 player server?
No. Everything runs on the server. Players join with connect and the address in the console.
Why can only 4 people join my server?
A lobby has reserved it, which caps co-op at four. Set sv_force_unreserved 1 in server.cfg and have players join by address.
Why are players five to eight stuck spectating?
The multislots plugin is missing or failed to load. Run sm plugins list and check the error log in addons/sourcemod/logs.
What is the highest sv_setmax I should use?
31. The command accepts 32, but the L4DToolZ author recommends 31 at most because higher values have crashed servers.
sv_setmax is an unknown command. Why?
L4DToolZ is not loaded. Check plugin_print in the console and make sure the files sit directly in left4dead2/addons.
Which plan do I need?
Stock co-op runs on 2 GB. Eight player co-op with plugins and a few custom campaigns is better on 3 GB, and a long plugin list with many Workshop campaigns can use 4 GB.
Is this an official Left 4 Dead 2 server?
It is a dedicated Left 4 Dead 2 server that you rent and control. GamezServers is not affiliated with the game's developer or publisher.
How much RAM do I need?
Start with 8 GB for most games. Choose 4 GB for small or older games, and 12 to 16 GB for big worlds, many players or heavy mods. You can change plans any time.
How do my friends join?
Share the server address from your panel. Most games join through a direct connect or server list screen, and the Invite friends button gives you a join page to send.
Can my friends and I split the cost?
Yes. At checkout choose "Me and my friends" and up to 10 people each pay their own share with their own card, on any plan length, from 3 days to a year. It is not a payment plan: nobody pays in parts over time, each friend simply pays their own share. You pay yours, send each friend their link, and the server starts straight away. Each share includes a $1 payment fee.
Can I build a custom plan?
Yes. Every game has a Build your own page: pick any amount of RAM up to 32 GB, any length from 3 days to 1 year, prepaid or a subscription, plus your server type and settings. A custom size costs 15% more per GB than the standard plans next to it.
Can I pay once instead of a subscription?
Yes. Pick Prepaid and pay once for 3 days, 30 days, 6 months or a year. Nothing renews: when the time is up the server pauses and keeps its world for 14 days. Add time or switch to a subscription from your panel any time. Short rentals cost more per day, since every server is set up from scratch.
How fast is setup, really?
Your server starts building the moment Stripe confirms payment. Most are online in under a minute, and the address and login appear on your dashboard automatically.
