Halo Wars 2 Serina DLC Full Breakdown


So today was the day that the new Halo Wars 2 DLC released. This being the leader Serina, and the two ODST missions entitled Operation Spearbreaker. For more information on the story DLC you can read more in my article here. This article will cover the full breakdown of the leader Serina, instead of just a sneak peak like the previous article. Below you can find the information on the new units, the new art, and the new achievements, as detailed by 343 Industries. You can find the link to the original article by 343I at the bottom of the page.


Serina (Introduction)

“Serina was activated on January 7, 2530, by Daedalia Technology, a Martian firm well-known for the seeding and development of artificial intelligences for military and corporate markets. Serina was their greatest work of that era, an omni-capable second-generation “Smart AI” that displayed both impressive intellectual capacity and remarkable computational efficiency. Her assignment to the UNSC Spirit of Fire was fortuitous, despite a somewhat rocky period of acclimation to the ship’s unorthodox crew. Under the orders of Captain James Cutter, Serina administered the deployment of forces on Harvest’s surface, and successfully managed later campaigns on both Arcadia and the enigmatic Forerunner facility known as Shield 0459. Unfortunately, the life of a smart AI is limited, and their constructed minds cannot be slowed or stopped. While the Spirit of Fire drifted in the void after their victory over the Covenant at Shield 0459, Serina imagined, planned, and built for a future she would never see.

Serina had a remarkable aptitude for research and analysis, and her thoughts often turned to the work of Ellen Anders. In particular, the Professor’s early work on vacuum energy extraction—and it’s potentially useful side effects with regard to heat siphoning—fascinated Serina. Serina’s experimentation and engineering expertise gives her access to unique cryotech-enhanced units and abilities that can freeze targets and render them inert. Frozen targets are immobile and unable to perform any actions, but don’t take damage unless they are shattered. Frozen units that take a significant amount of damage or are targeted by certain special abilities (such as Seismic Charge) will shatter and immediately take a massive amount of damage. Frozen units that are left alone will thaw out after a short time, and do not suffer the damage spike.”


New Combat Mechanics

Chill: A unit that is chilled is slowed not only by reduced movement speed, but they also capture points and zones slower, and do less damage. If units are not affected by a chillsource for a short time, they will revert to normal behaviours. There are several sources of chill, including Cryo Troopers, The Bison, Frostraven, auras from Cryotech Advances or Ice Barrier and active leader powers.

Freeze: After a unit has accrued enough chill, they become frozen. They cannot move, attack or do any actions while in this state – this includes buildings. After a time, they will eventually thaw and go back to normal, suffering no further effects from being frozen. If a frozen unit is attacked, they will not be hurt unless they get shattered.

Shatter: If a frozen unit takes enough damage or is attacked by certain weapons, they will be shattered. This will cause a large damage spike, but will also instantly thaw them, allowing them to move and attack as normal (assuming they’ve survived the attack).


New Units

TUNDRA BISON: “The Tundra Bison is a hero vehicle available to Serina. In Serina’s employ it is a heavily-armored and shielded vehicle that synergies 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 Tundra 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 defences and the area of the chill aura. “


FROSTRAVEN: “The Frostraven is an aerial support vehicle unique to Serina. It is equipped with a vacuum energy extractor, nicknamed the cryo ray, which chills and then freezes enemy units. The Frostraven can also unleash its special ability, a barrage of concussive seismic missiles> which slow and damage units in the target area, shattering any frozen enemies. With the Chill Out upgrade the Frostraven’s cryo ray becomes even more powerful, chilling and freezing the targeted unit faster. “


CRYO TROOPER: “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. If the chill gets intense enough the target will be frozen. 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. “


New Abilities

ICE BARRIER: “Serina learned much about warfare from monitoring the activities of Sergeant Forge and Captain Cutter, including the value of controlling the flow of battle by manipulating the terrain. Among her tools to accomplish this is the Ice Barrier leader power, which creates a frozen block at a target location. The block of ice can be used to bloc choke points and disrupt enemy formations and will chill nearby enemies. The barrier can be shattered by enemy attacks. Ice Barriers are weaponized versions of an Ander’s early, ultimately unsuccessful, experiment with creating compact, zero-point energy condensers. Activation overloads the delicate barrier generators, but not before the area around them are drained of thermal energy.”


GLACIAL STORM: “Does an initial impact with damage and chill, and then spreads out to cover a fairly large area, chilling any units in its vicinity over a healthy duration of time. “


CRYO MINE: “Highly effective mine detonation, which both deals damage, then freezes any unit enemy caught in the blast.”


CRYO BOMB: “Causes a small amount of damage and freezes anything short of a hero and uber units caught in the blast.”


SEISMIC CHARGE: “Does mild damage by itself, but shatters any frozen units in the vicinity for large damage.”


Additional Abilities

Cryotech Advances: Gives chill abilities to various units: Turrets, Drop Turrets and Energy points gain a chill aura. Cryo Troopers gain a shield and a chill aura. Kodiaks and Siege Turrets do chill with each shot.

Cryo Drop: Drops 2 squads of Cryo Troopers, 2 Scorpions and a Frostraven, accompanied by 3 seismic blasts to damage or shatter any squads in the area


Of course as is standard with Halo Wars 2 DLC, there are also some new achievements, which are listed below:

Nothing too difficult, then?: Win 3 matches as Serina (Multiplayer, Skirmish or Blitz) 

Freeze!: Freeze 50 squads with Cryo Abilities (Multiplayer, Skirmish or Blitz)
