"None will escape the area of impact!"

The Earthsplitter ordnance is a Terran Dominion artillery platform. It can fire traditional salvos at long range, or utilize shells contaminated with radiation or psycoactive drugs, and manned by Dominion troopers and Dominion laborers.

In the timeline where Arcturus Mengsk survived the Second Great War, Earthspliiter ordnance platforms were constructed on the field for use against the armies of Amon.[1]

Game Structure[edit | edit source]

The Earthsplitter ordnance is a 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 ob the objective. The attack so the Earthsplitter 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.

The model of the turret is taken from the turrets that surround Korhal Palace in the Heart of the Swarm mission "The Reckoning."[2]
