Dome of Light
Dome of Light is the sixth campaign level of Halo Wars. The level involves breaking through a giant, dome-shaped Covenant Energy Shield to discover what lies within. The main objective of the mission is to escort the Rhino tanks to the marked points around the map, defended by the Covenant, after which Serina will fire all tanks on the same point of the energy shield to break through it. The mission initially involves placing three Rhinos at the marked points but after a failed attack on the shield two more points are selected for Rhinos to be placed at. After the energy shield is broken through, the player is then given 40 MAC shots to destroy the Covenant base within and complete the mission. This is another level in which the player is aided by computer-controlled units.
On the UNSC Spirit of Fire, Professor Ellen Anders reveals her latest findings to Sergeant John Forge and Captain James Cutter: a massive Covenant energy shield blocking their view of a portion of the planet. The Covenant are clearly up to something beneath the shield, but the Spirit of Fire can't use its weapons to take down the shield without risking destroying whatever is beneath. Anders realizes that superheated plasma can overload the shield dome's power supply and a plan is formed to use plasma-based M145D Rhinos from the UNSC Pillar of Autumn to safely take down the shield.
At the Arcadia ONI facility, the first attempt to destroy the shield has no effect and instead draws the wrath of the Covenant. As Anders struggles to determine how many Rhinos they need and to calibrate the shots, UNSC forces struggle to repel Covenant forces and place the Rhinos into position. Finally, after encountering heavy resistance, the Spirit of Fire's forces are able place five Rhinos from the Pillar of Autumn into position and together, they take down a section of the energy shield.
With the barrier penetrated, the player takes control of one of the Spirit of Fire's MAC turrets and destroys the air defenses and shield generators beneath the dome. Serina eventually takes over if the targets are not taken down in a timely fashion and finishes the job. With the shield down, UNSC forces are able to investigate what the Covenant were hiding beneath.
The UNSC Spirit of Fire is seen floating in space.
In the bridge, Captain Cutter and Ellen Anders are standing around the central holo-table, which shows a large holographic dome, with red dots floating above and around it. One of the red dots enters the dome. Sergeant John Forge is standing behind Cutter.
On the holo-table, holograms of three boxes appear outside the dome, and begins to discharge large beams on to the dome. The dome hologram disintegrates after a few seconds.
Anders turns and gives Forge a quick smile.
Cuts to the Arcadia ONI facility. Anders is in a tower next to the UNSC Fortress. A Rhino moves away from the base and heads for the firing position.
The Rhino approaches firing position and opens fire, hitting the dome shield, which shows barely any reaction. Covenant air units emerge from the dome and attack the Rhino.
The Banshees destroy the Rhino as Spirit dropships approach the UNSC base.
Red Team, Marines, and Forge's Warthog fend off the Covenant troops.
When a Rhino is requested at the landing pad:
A Pelican arrives and deploys a Rhino.
The Rhino gets to its position.
ODSTs arrive in SOEIVs, and hold position next to the Rhino.
The mark appears on map. Two Covenant Halls occupy that location.
The UNSC forces destroy the Covenant Halls.
The second Rhino is deployed at the landing pad, and reaches the second position. More ODSTs arrive and hold position next to it.
The Rhinos fire at the energy dome, but to little effect.
The third Rhino arrives at the air pad.
A Pelican lands and picks up the Rhino, transporting it to the third position, which is also defended by the Covenant. The third Rhino reaches its marked position.
With the combined fire from all three plasma Rhinos, the shield dome begins to falter. A pair of Locusts appear on the far side of the ONI base.
The UNSC forces eliminate the Covenant at the fourth position, and the fourth Rhino gets to the marked position.
The UNSC forces clears the fifth position, and the fifth Rhino arrives at its marked position.
The Rhinos fire. A section of the dome shield falters and opens up.
Screen changes to the MAC reticule.
MAC opens up. After a few rounds, Serina takes charge.
The Covenant structures exposed under the dome's faltered section are destroyed.
