- Nerves of steel and hands of frost.
- Cryo Troopers replace Hellbringers in Serina's combat force. Fury runs hot and
- cold, as evidenced by Serina's plans for a cadre of cryotech—equipped infantry.
- Cryo Troopers are armed with a portable cryo spray which deals damage and
- inflicts a chilling effect on enemy units. This can shut down enemy vehicles and
- structures [including turrets], temporarily shutting them down even if they are
- not subsequently shattered. They can be upgraded with advanced cryo
- systems, which increases the damage, range, and area covered by the chilling
- field of their spray.
- Hellbringers are qualified to maintain, operate, and deploy a number of specialist
- weapon systems in the UNSC arsenal. This includes a range of incendiary,
- thermobaric, energetic, chemical, and biological weapons that most UNSC
- personnel are not even aware of. Serina reasoned their hazardous material
- qualifications and daredevil reputation made them well—suited for field testing
- experimental cryotech weaponry. Who better to strap on experimental and
- unstable power cells that tap strange energies than Marines who routinely
- wear volatile chemical packs into battle? She was probably right, if the spirited
- discussion about her cryotech weapon templates among the Spirit of Fire's
- Marines is any indication.
