You can mutate the hell out of these. Mine pop at 3800 health and 860 melee. After points and imprints i can put them to 4,100 health and 2,100 melee. The cryo sick timer is as fast as a giga so i bring 20 to cave pvp. Throw them all down at once in a safe location. Once they wake you put one on your shoulder and the rest on follow, pop a beer, put them all on aggressive and grab a flame thrower. The most fun you will ever have I swear lol
