Delta was a Ranked Server exclusive for any players ranked from SFC (Sergeant First Class) up to GOA (General of the Army). It is a unique server because it requires a Kill/death ratio requirement of at least 1.20, to a max of 100. That means that only hackers or the most elite players can enter this server. It is usually empty because there are so few players that meet that requirement, and even fewer that would risk their KDRs' to play there. Exclusively, Delta comes with its own Performance Record, meaning that any kill/death and other accolades achieved here will be added to a separate record on the CA website. Delta offers a 20% Increase in GP,and a 40% Increase in EXP, the most given in any Server so far.
Recently many people are getting suspended for 7 days even for doing legit, non-powerleveling games of Grave Digger-Capture the flag-Pistols only. Nexon made a poll on the official forums asking the community whether they wanted to keep Delta or bring Kilo back, and Kilo won 90% to 10%. Therefore, Delta was removed from the game and was replaced by Kilo.
