KC3 is an Game Player, which is a Chrome Extension allowing Admirals to play KanColle by fetching API links for you, remembering and re-using it until you specify to get a new link, and ultimately adds convenience by displaying game information in a user-friendly manner.

A one-click install from the Chrome WebStore and you're set!

Region cookies allow login even without VPN!

This is a continuation of KanCo! Tools (KC!T), but will carry "KC3" as its new name. This should avoid confusion with KancolleTool (KcT), which is a totally separate project, and is a primary suspect in the Spring 2014 bans.


The extension is available on the Chrome WebStore, don't worry it's free. This ultimately solves the problem with KanCo! Tools wherein Chrome automatically deletes, manually installed extensions.

Once installed, open the KC3 menu on the top-right of your Chrome (shimakaze icon), and select "Get new API link" this will lead your to the DMM website. Make sure, you have Region Cookies and Game Redirect enabled.

Command Center Play anytime!
This is a special game page where you can play using API link. Each time you open it will use your latest API link. No need to copy and hide it somewhere else, the app itself remembers your API link. If you want to refresh the API link, there's a separate feature for that.

Admiral's Panel See everything!
A very useful tool, reminiscent of KancolleViewer (KCV). Mostly of the same purpose, to show you useful and important game data in a user-friendly way. Although, alot more is planned for this tool.

This can be accessed through the Chrome DevTools (HotKey: [F12]). A new tab is added on the devtools panel where you can access your game information.

Admiral's Panel also works if you play on DMM game site itself!

Region Cookie Method LOGIN EVEN WITHOUT VPN!
If this is enabled, you won't need VPN/Proxy to access the game on DMM website. You just need to go there on DMM, set the language as japanese, and its done. You can now go to the game page and play without restriction. No more API links.

Getting new API link Fast and Easy Refresh Link!
If you need to refresh your API link (maintenance or monthly reset), or just prefer other third-party viewers, just enable "redirect" on the menu, and everytime you login to the DMM game page, you will be redirected to the Command Center, where you can view your API link.


Is this extension ban-safe?
KanCo! Tools never had any reports of users getting banned, even after the Spring 2014 elimination rounds! As this is the continuation of that project, you can rest easy.

I've been observing the API for months, as some of you might already know. I've been doing some quick API decodes each update for fast and accurate information delivery to the community.

I know what is illegal and what's suspicious here on the back-end. This extension never makes "synthetic" / "unnatural" API calls to the server. The information shown on the Admiral's panel is from the Chrome's Network Logs (devtools), see methodology section.

Is this extension hacker-safe?

1) This extension does not store or send your username/password to anyone or anywhere. Users can inspect the extension's running code via Sources tab of developer tools.
2) The game API and the DMM website does not use https, so your packets are unencrypted and can be intercepted, especially when using VPN. I'm not into networking, so even I, can only guess on that possibility.

Region Cookies doesn't work! I still see Error Area.
As mentioned in the features section, when you're on DMM, set Language as Japanese on the top right on the website. Then refresh once, then just click on the Get new API Link from the KC3 menu again.

Tips and Tricks

Horizontal Player
