Overview
City of Heroes uses a program which runs on your computer called the Game Client (and its associated game files) to generate the graphics you see and the sounds you hear. It figures out what you have clicked on and it handles the typing you do at your keyboard. The client is constantly sending information to the Server to tell it what powers you activate, what attacks you make, how you move and turn, and the messages you type to other people.
The Server is constantly sending information to your client to tell it what everyone else in your zone or mission are doing. The client shows you their actions based on that information. If something interrupts the flow of that information then everyone else will stop moving on your screen. If the flow of information is interrupted long enough then you are disconnected from the server, typically with the message: "Lost connection to mapserver".
When a new version of the game client is available it has to be downloaded to your computer before you can use it. A program called a Launcher checks for and downloads new versions of the client and all its associated files.
The launcher is used to start City of Heroes, or any other game it is programmed to update (including Beta Services).
Facts
- The same game client is used to play both City of Heroes and City of Villains, on ALL operating systems.
- Windows OS runs the client natively.
- MacOS (under Intel processors) and Linux use WINE to run the client on a Windows Subsystem layer.
- All character data is stored on the servers. You can access your account and character data from any computer that has the game client.
- One caveat: files such as Architect Entertainment save files, Character Select sorting, and Player Ratings, are stored in text files on the player's hard drive and are not accessible from other computers.
- Patches are installed prior to logon and the latest version is required to play.
- The client loads in two stages:
- The Launcher, which downloads patches and checks the client for the latest version. Examples of Launchers include Tequila & Island Rum.
- The Client, which contains the game itself. The client cannot be run directly by players, as a launch string is needed to inform the client of the patch version the server currently accepts.
- Since the Sunset, NCSoft's keys, game cards, and promo codes no longer work. There is no CD Key required to install the game client.
- The Launcher can downloaded to install the game without requiring any CDs or DVDs. Use of NCSoft Client files pre-Issue 24 will cause issues in patching, and should not be attempted.
- Note: A new installation using the Launcher will download the entire client, and may take a long while.
- Windows users can choose the where the game client is installed at time of installation. After installation, it can only be changed by editing the Registry (registry location: HKCU/Software/Cryptic/Coh )
- Mac/Linux users will follow the WINE convention of installation, which will be located on their "Wine C Drive".
- It is possible to replace almost any resource (in game map, sound file, etc.) using the data directory.
- This does not modify any resource/file. This adds a directory which the game client then interprets as replacing the resource once the game is launched. Removal of this change simply means deleting the \data directory. More info below.
Launchers
There are two Launchers for Homecoming: City of Heroes.
Tequila, which is the Windows-specific launcher for Homecoming. It is independently-made, and was made to be a simple application to patch a collection of files. Island Rum, which is a Mac Installer and Launcher for Homecoming. It is maintained by Manga, and handles the installation of Wine, the City of Heroes client, and patching the client before play.
The Homecoming Launcher was released on October 13th 2020 as an alternative to Tequila and Island Rum; it allows launching the game on Windows natively, and on Linux and MacOS via Wine.
Launching the Game
PC
These can be run from the command prompt or entered into your shortcut. You can do the latter by right clicking on your shortcut to the Launcher and selecting properties then adding these to the end of the target box.
CityOfHeroes.exe -project "coh"
- NOT SUPPORTED Launches the game client without looking for the launcher, using the North American servers. If any patches have been applied since the last time you used the launcher, you may be able to login, but you will get a version conflict.
CityOfHeroes.exe -project "eucoh"
- NOT SUPPORTED European Servers version of skipping the launcher.
CityOfHeroes.exe -project "cohtest"
- NOT SUPPORTED Training Room version of skipping the launcher.
CityOfHeroes.exe -compatiblecursors 1
- Uses compatible 16-color cursors to solve compatiblity issues with Windows Vista and others. Please note that this has since been integrated into an option in-game.
CityOfHeroes.exe -usetexenvcombine
- Enables simple rendering path, which may help fix issues with certain video cards and drivers.
CityOfHeroes.exe -renderthread 1
- Forces the game to run using more than one proccessor/core, rather than using only one. NOTE: Though the game does this by default now, this command is still a valid option.
CityOfHeroes.exe -renderthread 0
- Forces the game to run using only one processor/core, rather than using two. This may be needed to work around buggy drivers, or on Linux.
CityOfHeroes.exe -maxinactivefps 5
- Limits the graphic display update to 5 Frames Per Second when COH is not the foreground application. The number can be set to whatever maximum framerate is desired.
CityOfHeroes.exe -stopinactivedisplay 1
- Freezes the graphic display update when COH is not the foreground application. This can greatly reduce processor utilization when running multiple game clients on the same computer.
CityOfHeroes.exe -fullscreen 1
- Makes the game launch in full screen, regardless of what options are set in-game. To force the game not to launch in full screen, -fullscreen 0 should be used.
CityOfHeroes.exe -screen x y
- Makes the game launch in a window with a width equal to x and a height equal to y.
CityOfHeroes.exe -console 1
- NOT SUPPORTED Launches the game client displaying a console with each element being loaded. Useful if your client is freezing on load, if you want time statistics for how long it takes to load, or to see other debugging info.
CityOfHeroes.exe -exitlaunch [command line]
- NOT SUPPORTED The game will execute the given command line on close. Used internally for issue preloads, but can be set to execute any program when you finish playing.
CityOfHeroes.exe -project coh -launcher
- NOT REQUIRED SINCE HOMECOMINGStarts the game as if it had been run from the NCsoft Launcher, unlocking the Wisp Aura.
Mac/Linux
- Please see: City of Heroes on Mac
- Please see: City of Heroes on Linux
Mac and Linux client options for Homecoming all use the same client strings as Windows. In Homecoming Launcher, you can set these under "Settings" and "Extra Launch Parameters" for the client you want to launch, regardless of the operating system.
Running the game from a DVD-R
If for some reason you would like to run the game from a DVD-R, or maybe a 4GB flash drive, this is possible. Being a read-only device, a DVD-R will only work as long as you burn the latest version with the current patches. However, if your goal is to play at a Net Cafe during a weekend away from home, this will be more than enough.
The steps are:
- Click Start, Run, and enter regedit. Navigate the left panel to HKEY_CURRENT_USER\Software\Cryptic. Right-click the Cryptic folder and select Export. Save as Settings.reg somewhere.
- Burn your City of Heroes folder and the Settings.reg file to a DVD-R.
- Take the DVD to the computer you want to play the game on. Go to the DVD drive and double-click the Settings.reg file. You only need to do this step the first time you run the game on a computer.
- Click Start, Run, then enter "D:\City of Heroes\CityOfHeroes.exe" -project coh. Replace D: with whatever letter the DVD drive is.
- Play! You can change the graphics settings on the new computer to whatever you like, and they'll be saved locally.
If you find yourself playing on an unknown or relatively low performance system, remember to click Settings and adjust the graphics settings to low, and maybe enable windowed mode. This gives the game client the best chance of running properly. This should be done before logging into the game with your username and password!
Registry information
The game stores its configuration information in HKEY_CURRENT_USER\Software\Cryptic\Coh; even if you installed City of Villains, the key name is still Coh.
- If you use the Test server, its configuration is stored in HKEY_CURRENT_USER\Software\Cryptic\CohTest.
- If you use the Beta server, its configuration is stored in HKEY_CURRENT_USER\Software\Cryptic\CoHBeta.
The Installation Directory parameter is useful in case you want to move the game client to another directory or partition. Enter the full path to the game's executable.
The VerifyOnNextUpdate parameter is created every time the game crashes. When the game starts, it checks for this flag in order to decide whether to verify all files for corruption before loading the file. Thus, clearing this flag is a good way to avoid the slow verification process.
If you crash often and would like to skip the verification process every time, simply create a text file named NoVerify.reg with the following contents, and double-click it before loading the launcher:
REGEDIT4 [HKEY_CURRENT_USER\Software\Cryptic\Coh] "VerifyOnNextUpdate"=dword:00000000 [HKEY_CURRENT_USER\Software\Cryptic\CohTest] "VerifyOnNextUpdate"=dword:00000000
Network information
Servers
Your computer needs access to the internet, of course; and to be able communicate with various servers (not just the game servers). Certain ports (see below) may have to be opened.
NCsoft say (Article 884) that all servers "are centrally located in Dallas, Texas, as of July 29, 2010. Connection speed and performance should be the same throughout North America", and also state that the "four servers that used to be part of the Europe or 'EU' territory were merged into a single list on May 10, 2011."
Players located outside North America (such as Australasia, Europe, and elsewhere) may sometimes find that their playing experience is improved if their computer uses a DNS server located in America. An example would be the Google Public DNS
In the event you have a working internet connection, but cannot play City of Heroes, it's possible there may be an issue with the connection between your computer and one of these servers. If this is the case, you can troubleshoot this problem using diagnostic tools, seek assistance from other players on the Official Forums, or lodge a support ticket with NCsoft.
A small NCsoft program called Game Advisor can be downloaded and used to gather information about your computer, including network tests to various servers needed to run City of Heroes. If lodging a ticket with support, the report produced by Game Advisor should be included.
Running Game Advisor includes tests to certain network addresses and ports, and more. Some players may wish to run manual tests on these IP addresses and ports using tools such as ping and traceroute. A partial list of the IP addresses and ports tested, as of June 2012, is shown below.
Note: these could change at any time at NCsoft's sole discretion, of course; and that failure on any one test may not be the cause of any issues with running the game.
Game Ports
The game client is somewhat Firewall and NAT friendly. However any issues can be resolved by ensuring the following ports are open:
- TCP 2104
- TCP 2106
- TCP 443
- UDP 7000-7200
