Most notable of these changes is that Trioxin (spelled Tryoxin in these particular films) zombies are no longer the indestructible juggernauts of the first movie, but instead much weaker than even "Romero zombies." Several times throughout the movie they are seen to be dispatched with no more than a few body shots, sometimes as few as two hits will end their undead life. Prior to this film, nothing short of incineration or electrocution with extreme high voltage would terminate a Tryoxin zombie.
