As of February 17th, GunZ 2: The Second Duel has been released on Steam's Early Access program, featuring several new additions to the game, including a new playable class, two new maps and a new game mode.
However, the launch server has been gaining an excessive amount of traffic, causing it to crash repeatedly. In order to keep traffic down, MAIET has issued a temporary server limit of around 1,500 players. Along with the limit, players have reported several issues including menu lag, issues with joining active matches and more.
