It was the most feared program during that time that it destroyed other programs left and right. It also managed to win 3 MSL awards and 1 OSL award.
However, on 2007, the program became more less efficient and then started to show weak performances after failing to destroy 'Bisu' (created by MBC, but the rights was later bought by SKT).
CJ tweaked the program at times to finally destroy the Bisu but to no avail...
A year later, to make things more worse, Hwaseung managed to obtain some IPXZerg 2.0 data and modified it to match that time's high performance standards. The project was called "Jaedong".
After years of drought, CJ finally came up with something, IPXZerg 3.0. However, it was still in alpha stages but despite this, it still managed to destroy everyone in Blizzcon. It entered beta stage during the Winners League and destroyed almost everyone.
IPXZerg 3, project "EffOrt" was finally released after days with hopes that it will SAVE THEIR EFFORTS.
