Download CO game client

MD5 code is used to check the integrity of your download. (This check is optional)

Install your download and you’ll find a programme icon on your desktop.

Double-click it to start auto-update for your CO client. (Or you can manual update, click to know how)

You’ll see auto-update window being closed and restarted automatically for several times within the whole process.

Never mind. This is client patch files being downloaded and installed one by one.

(If you are vista users, you need to disable vista UAC to complete auto-update)

Now you can select the server you want to have fun or build order with.
