Phoenix Logs/UNSC Units/Bison

Heavy—duty cryotech support vehicle.

The Bison is a hero vehicle available to Serina. In Serina's employ it is a heavily-

armored and shielded vehicle that synergizes well with other cryotech vehicles

and abilities. It is fitted with a powerful Coldsnap launcher, which fires

experimental cryo shells that damage and chill enemies caught in its area—of—

effect. The launcher can be upgraded, which increases the launcher's range, rate

of fire, and chill effect. When the Bison deploys it leeches ambient heat energy

to augment its defensive systems, creating a chill aura that affects nearby

enemies. These systems can also be upgraded to further boost defenses and

the area of the chill aura.

Bisons are versatile, durable vehicles that served in most groundside combat

elements of the old Colonial Military Authority [CMA] in a number of roles,

including armored personnel carrier and recovery vehicle. It remains in service

with several UNSC Army units and local militias [such as the Sedran Colonial

Guard]. The variant designed by Serina uses the proven chassis as a testbed

which holds a vacuum energy siphon, scientific instrumentation, and cryotech

weaponry in one mobile package. As there are no Bisons aboard the Spirit of

Fire at present, Isabel has looked at improving and repurposing the siphon with

her own research data on Forerunner vacuum energy cells, but the delicacy and

intricacy of Serina's manufacturing template complicates this effort.
