Flood Carrier Form
"A Flood Carrier form is so called because it carries a payload of gestated Flood Infection forms. This creature is an evolution of a Flood Combat Form that has become too badly damaged to be effective in battle. This is an incredibly efficient use of what would otherwise be a battlefield casualty. When it finds itself in the proximity of suitable hosts, the Carrier Form erupts in a concussive blast that is not only dangerous to bystanders, it also unleashes and disperses its cargo of Infection Forms to devastating effect."
