Considered to be the largest single concentration of Goo known to exist. Only the largest of Mother Goo can begin the transformation into a Purger. Combining with other Mothers accelerates the transformation.
Like other formless Goo, the Purger can climb onto high terrain and attack enemies from safety.
Protect Purgers with Tempests, as they have no anti-air capabilities.
Attacks from a Purger take time to travel to the intended spot - be sure to lead your attacks.
