NORTH SPIRE/FORERUNNER LAUNCH
NOT ON MY WATCH
Stop the Forerunner ship from launching.
Pelican Transports can be used to quickly move your army around the battlefield.
While the Banished are heading towards the Forerunner launch site, a Condor Gunship approaches it and starts the assault. The Banished ignore the Condor as it attacks the launch site, and an EMP bursts from the launch site, destroying the Condor.
Back on Sunray 1-1's position, the light bridge behind them is out.
The countdown timer starts at 15 minutes and Sunray 1-1 starts advancing.
Sunray 1-1 approaches one of the charging columns. A Huragok and Banished infantry are defending it.
Sunray 1-1 clear the Banished out from the charging columns.
Sunray 1-1 attacks the charging columns and, once destroyed, the ground shakes.
Some Aggressor Sentinels approach the charging column site and Sunray 1-1 engages them.
Quinn finds two potential spots for the base construction.
Sunray 1-1 approaches the closest base site and calls in a base drop. They also call the Colossus drop while they are waiting for construction.
A Colossus drops in to the base.
Reaching the charging column found earlier, a Spirit Dropship approaches and drops off Banished units to defend it.
While clearing the area, the base construction is completed.
Once the area is clear, the Colossus stomps on the charging column and shuts it down.
On the launch site, the ship shakes violently and the timer extended by 10 minutes.
Sunray 1-1 decide to clear the area of Banished silos for extra resources.
Once enough forces are built, Sunray 1-1 starts advancing and encounters a Controller Sentinel fighting Banished units.
Quinn notices the tether beam linked to the Controller Sentinel.
Once the Banished are eliminated, the Controller Sentinel resumes patrol.
They start tailing the Controller Sentinel from a distance.
Reaching the power node tethering the Controller Sentinel, Sunray 1-1 start capturing it to disable the shield. Once completed, the Sentinel's back becomes exposed.
Once destroyed, they approach the second charging column. Nearby, they spot a Banished base and engage it while avoiding another Controller Sentinel that was on patrol.
If the timer reaches 5 minutes before launch.
When attacking the charging columns while clearing the area, some Aggressor Sentinels appear and the UNSC quickly defeats them. Once defeated, the Colossus stomps on the column and the charging stops, as the time extends again by 10 minutes.
The Forerunner ship shakes again and Colony give another warning.
The UNSC goes to the power node to shut it down. Once it's shut down, the UNSC uses a Holo-Decoy to distract the Controller Sentinel and destroy it from the rear.
If stalled to the last five minutes.
The UNSC advances again and reaches another charging column.
The UNSC clears the area of Banished and Aggressor Sentinels after damaging the column. The Colossus stomp on the column to deactivate it. The timer extends by 10 minutes.
The Forerunner ship shakes again.
The UNSC advances to the last charging column while also spotting a Controller Sentinel and disabling another power node. Once exposed, a Holo-Decoy is used to distract it while the UNSC destroy it from the rear.
If the player stalls to the last five minutes for third time.
Spotting the final charging column, they encounter a Banished base and a Controller Sentinel nearby.
After clearing the area of Banished and destroying the charging column, the Colossus stomps on it.
The Forerunner ship shakes from disabled charging energy but the timer is still counting.
Approaching the launch site, Colony orders all of the Banished troops in the area to stop them.
The battle breaks out at the launch site.
The UNSC clears the area of the Banished. Once the area is clear, they regroup at the terminal.
Once Sunray 1-1 reaches the terminal, they shut down the ship.
A portal opens and a Hunter Captain comes out of it, while a Spirit Dropship drops some infantry support.
The UNSC start to engage the Hunter Captain. When it reaches 66%, a portal opens and transports the Hunter Captain away. Goliaths start to appear and heal the Hunter Captain.
After defeating the Goliaths, the UNSC continues to engage the Hunter Captain. When it reaches 50% health, it teleports again and the UNSC have to clear the area to avoid orbital bombardment.
More Banished drop into the field while Goliaths heal the Hunter Captain. The UNSC focuses fire on Goliath and Banished before continuing dealing with the Hunter Captain. They also have to avoid glassing beams.
After a tough fight, the UNSC defeats the Hunter Captain.
The UNSC watch the launch site as Sunray 1-1 are approaching the ship with in Hornets and throw satchel charges onto it.
The UNSC moves away from the launch site as Quinn activates the terminal, lowering the ship further into the ground. As the Forerunner ship drops, the explosives detonate and is finally destroyed.
Hornets arrive at the Landing Zone to extract Sunray 1-1.
Some Pelicans arrive at the other Landing Zones to extract infantry.
Vaughan and Quinn sit on the Hornet, passing through UNSC forces that are on site.
Another Hornet and Pelican follow behind Vaughan and Quinn. The scene cuts to black as the Pelican fills the screen.
