Phoenix Logs/UNSC Units/Cryo Trooper

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.
