When the Great War ended, and Zimnyaya was forced to surrender, he left a war prisoner he hadn't told anyone about behind, locked in a bunker. Without any food, he quickly passed away, but his body was exposed to radiation from nuclear bombs for years and, after a long time, it came back to life... as a zombie! Welcome back, Sergeant Hull Head, you look different now!

Sergeant Hull Head is a Tank with High Life and a super cool trait: Gravedigger! This trait blocks Possession and Nightmares. While he's alive and on the team, he can block resurrections on the enemy team! The Sergeant can increase his Maximum Life and Heal himself; he can block Torture skills and protect against Fire attacks! There's one more trick up his zombie skill: He can apply Blind and Total Blind to his enemies!
