Sudden Attack

Deathmatch, Destruction, capture the flag, or custom modes (sniper only, pistol only, or knife only).

Both teams must satisfy certain conditions, such as defusing a bomb, successful planting and detonation, or achieving a certain number of kills.

By September 2011, Sudden Attack's Taiwanese publisher, Gamon, did not renew its contract with Nexon to operate the game in Taiwan.

A few months later, Gamania, which had published many of Nexon's games including Counter-Strike Online, obtained the rights.

The game's closed beta started on February 22, 2012 and became fully operational on April 18.
