Hellbat/Hellion rangers are special forces employed by Nova in Co-op Missions. They replace the standard hellbat and hellion. They can transform into either hellion or hellbat rangers.
Hellbat rangers deploy in teams of two from Nova's factory for a cost of 500 minerals. Compared to normal hellbats they have increased HP and damage, and retain the ability to transform into hellions. Hellbat rangers are also the cheapest deployable unit after the Raven Type-II.
The Hellion/Hellbat transforms from one mode to another.
