Plutonium

Well as you can see in task manager it's downloading so just wait.
Some of the files it downloads are 2GB+.

We don't support SP.

Well i also apologize for responding so late, your post somehow got lost in my notifications.
Are you still having this issue?
When your server starts does it show that it's running on port 4977?
Try also forwarding tcp traffic for that port, not just udp.
Also i suppose that blacked out part is your pc's internal ip? Make sure that is the correct one (get it by typing ipconfig into cmd).
No need to black that out btw.

Known issue, i also don't see all of them.
Just connect manually via the console, here's an online list you can use http://api.raidmax.org:5000/servers (switch to the t6 tab).

Please refrain from creating multiple posts on the same issue (refering to your "really" topic), if you get no responses to your posts it most likely means the people who have seen it don't know the answer to your question/don't know the solution to your problem.
Which mod are you trying to run?
Does it work without the mod? If yes, well you already know what is causing the problem.

You made mistakes in your includes, there is no zombies_zm.gsc in maps/mp, it's in maps/mp/zombies, maps\mp_utility also doesn't exist.

#include common_scripts\utility;
#include maps\mp\zombies\_zm;
#include maps\mp\zombies\_zm_utility;
#include maps\mp\gametypes_zm\_hud_util;
#include maps\mp\gametypes_zm\_hud_message;
#include maps\mp\_utility;

If you're asking if there is a way for you or other modders to do that then the answer is no.
We will release more maps from mw2 in the future but they still need alot of manual fixing, no eta.

Installing dx9 is the solution to that error.
Did you by any chance download any dlls that the game told you were missing manually? If yes, delete them.
You're saying nothing happens after starting t6rmp.exe? Make sure no instances of the game are still open in the background (check task manager).

Post a screenshot of your port forwarding settings.
What do you mean by having to start plutonium before starting the server? You start the bootstrapper which starts mw3.

This is illegal af, better don't play or the police cops will come knockin'.
Look at the mw3 launcher, can't tell me that looks shitty. Even supports launching bo2, just doesn't have updater functionality for it built in atm.

Read the damned FAQ.

ffs..

Error: Failed to start launcher exit status - 1073741515 or 3221225781
Fix: Download and install https://aka.ms/vs/16/release/vc_redist.x86.exe Visual C++ 20015-19 x86 redist. Then relaunch the launcher.

I'm not into anime but it still cool.

I suppose you're talking about bo2?
Read the readme before asking questions.
But since i'm a really really nice guy i'm gonna paste the instructions here:

Change your name: click the tilde key ~ to open console then type: name <insert your name here> - You MUST change your name to play on public servers or you will be auto-kicked until you do!

Tbh, yes. Ghosts extinction isn't half bad, didn't enjoy the mp that much either, for the same reasons xerxes stated.
But iw5 and t6 already take up 101% of the devs' time, adding another game would just slow down progress on everything.
Wouldn't say it's absolutely impossible (don't turn this into "omg a new client is gonna come out", it's just my personal thoughts, i have 0 info on any new clients) that another game will appear on pluto after iw5 and t6 are finished but that won't be anytime soon.

You can't turn it off completely, you can only set it to "low".

Please read the FAQ before asking, thanks.

Post the contents of your startserver.bat

Error: context deadline exceeded (Client.Timeout or context cancellation while reading body)
Fix: Open command prompt in the folder that you have the Plutonium Launcher and type plutonium.exe -timeout 600 this will launch Plutonium.exe with a timeout for each file of 10 minutes. The timeout can be changed as much as you'd like. By default it is set to 60 seconds.

Please check the faq in the future before making a post, thanks.

Well you made a mistake while configuring your server.
Maybe you answered "n" to "use pluto t6 parser"?
Or you punched in the wrong rcon password.
Post a screenshot (or the text directly in code tags) of the "servers" section in configuration/IW4MAdminSettings.json.

Answer "y" to "Use PlutoT6 parser", this is plutot6 afterall so you need the parser for it.
Also is the rcon password (the one you also set in your pluto t6 server.cfg) actually "1111"? highly recommend that to change something more complex lol.
