Mgame USA just posted a press release to announce the start of their new MMOFPS - Operation 7. All CB testers must uninstall the old client and re-download the new installer. And all data for previous testers will be reset except their name.

Operation 7 is an online shooting game (MMOFPS) featuring a unique gun modification system.
In Operation 7, 5 types of different items including functional items can be equipped on the character. Also, there are 3 different designs for the same model or parts so each player can costomize their character appearance the way they want.
In addition, players' body movements while shooting, such as dashing or holding breath, will also influence destruction and accuracy.
