The Earthsplitter ordnance is a Terran Dominion artillery platform. It can fire traditional salvos at long range, or utilize shells contaminated with radiation or psychoactive drugs at global range. It can be manned by Dominion troopers and Dominion laborers for faster reloading times.
In the timeline where Arcturus Mengsk survived the Second Great War, Earthspliter ordnance platforms were constructed on the field for use against the armies of Amon.[1]
The Earthsplitter ordnance is an offensive artillery platform available to Arcturus Mengsk in Co-op Missions upon reaching Level 3. It has considerable range, which can be enhanced by upgrades at the engineering bay. Earthsplitters will fire randomly in the selected target area of a bombardment.
While the Earthsplitter ordnance itself costs no supply, by itself the platform fires at a rate of once every 30 seconds. This can be lowered by garrisoning Dominion troopers and Dominion laborers inside it, the the following firing rates:
15 (with 1 garrisoned unit)
10 (with 2 garrisoned units)
7.5 (with 3 garrisoned units)
6 (with 4 garrisoned units)
As such, it is important to have at least 3 or 4 units within each Earthsplitter to ensure a steady rate of fire. Alone these platforms do not do much, but in larger numbers they can continually shell an area for massive damage, aided by the random nature of their bombardments. Sufficient Earthsplitters can level incoming attack waves as they approach.
In addition, Earthsplitters can be salvaged for their full cost. This means that on maps where objectives may end up out of range, these platforms can be "leapfrogged" forward to an area where they can fire on the objective. The Earthsplitter's attack can be targeted through the fog of war, and briefly give vision of the area targeted.
The additional use of the Earthsplitter is for use with the Contaminated Strike calldown. Unlike the normal Bombardment, this calldown has unlimited range, but uses all Earthsplitters deployed. After around 6 Earthsplitters however, the Contaminated Strike zones begins to overlap for no additional effect.
Upgrades and Abilities[]
Bombardment
Bombards a target location, randomly delivering payloads near that location, that deal 100 damage to enemy ground units.
Usage
Hotkey
B
Cooldown
30
Notes
Each garrisoned units reduce the ability's cooldown:
Salvages this structure, removing it and returning 100% of its mineral and gas value cost. Salvage takes 5 seconds to finish. Warning: once Salvage is triggered, it cannot be canceled.
Loads all your Earthsplitter Ordnance with an experimental payload to target any location on the map. Payloads randomly land near the target location, saturating the area in Irradiated Biomaterial and causing all enemies who enter to take 5 damage per second for 20 seconds. Affected units cannot Cloak.
Psychoactive Payload: Contaminated Strike now cast Fear on enemy units on impact, causing them to run around in panic for 5 seconds.
Toxic Tyrant: Reduces the Contaminated Strike cost by 20% and its cooldown by 66%. Increases the Fear effect duration by 200%. Irradiate effect additionally increases damage received by 25% and deals 6.25 damage per second.

Required
Earthsplitter ordnance (Launch 1 experimental payload per Ordnance)
The model of the Earthsplitter ordnance is modified from the turrets defending Korhal Palace in the Heart of the Swarm mission "The Reckoning."[2] Conceptually they may be based on the drakken pulse cannon, a heavy long-range artillery weapon seen in several missions of Heart of the Swarm.
